An Epic Hygrometer PCE-WMS 1(Turbomachinery)
The Epic Hygrometer PCE-WMS 1 is what.
A hygrometer with a temperature meter and a processing unit with a network connection make up the thermo-hygrometer measurement system known as the Epic Hygrometer PCE-WMS 1.
The primary purpose is for measuring and keeping an eye on the climate in a warehouse or production area.
The device has a high degree of precision and dependability when measuring temperature and humidity, and it can store the information in an internal memory.
You can quickly access the data from any location using a web browser, and you’ll receive email alerts if the readings go beyond or below the predetermined boundaries.
Since you can attach up to 100 sensors to the system, you may expand its functionality to cover a variety of spaces.
The system’s plug-and-play functionality and tiltable, detachable display makes it simple to set up and operate.
For applications that call for continuous temperature and humidity monitoring in sizable areas, such warehouses or production halls, the Epic Hygrometer PCE-WMS 1 is appropriate.
It can assist you in ensuring that your products are stored in the best possible conditions, preventing condensation or corrosion issues, adhering to hygienic regulations, and enhancing energy efficiency.
The following are some advantages of utilizing the Epic Hygrometer PCE-WMS 1:
- It has extremely high accuracy and dependability for measuring temperature and humidity.
- It has an internal memory that can hold measurement data.
- If the measured values are above or below the predetermined limits, it can send email alarms and remotely query the measured data.Up to 100 sensors can be connected for coverage of various spaces and places.
- It has a tiltable and detachable display and is plug and play compatible.
- It is less than 6.4 lbs in weight and has an IP 40 protection class.
The Epic Hygrometer PCE-WMS 1 employs a direct technique of calibration, in which the meter is calibrated to a particular pure process gas and/or to the precise constituents of a mixed gas.
As a result, the measurement’s accuracy is increased because the calibration is now in line with the real process conditions and gas mixtures.
Additionally, if there are recurring fluctuations in the gas mixture, the system provides for several calibration groups that can be relied upon for enhanced repeatability.
Temperature and humidity are measured using the Epic Hygrometer PCE-WMS 1 using two variables:
relative humidity (% RH) and absolute humidity (g/m3). The ratio of the equilibrium water vapor pressure at a specific temperature to the partial pressure of water vapor in a gas mixture is known as relative humidity.
The mass of water vapor per unit volume of air is known as absolute humidity. For evaluating air quality and its consequences on materials, products, and health, both metrics are crucial.
The Epic Hygrometer PCE-WMS 1 employs the PCE-P18 sensor unit, which is connected to the data logger through Modbus, to monitor temperature and humidity. The sensor unit digitally transmits the temperature and humidity readings to the data logger, which stores them in internal memory.
Additionally, the data logger contains an Ethernet interface that enables web browser access to the data remotely. Additionally, the data logger features relay outputs that can activate pre-set alarms when particular thresholds are reached or exceeded.
The data logger also incorporates a tiltable, detachable display that provides additional information in addition to the readings that are now being recorded.
Up to 100 sensor units can be connected to the Epic Hygrometer PCE-WMS 1 to cover various locations and areas in a big space.
The data logger and the sensor units are connected by an Ethernet wire, and the sensor units are positioned at appropriate measuring locations in the warehouse or production hall. Because the system is plug-and-play capable, all that is required to get it up and running is some voltage.
The Testo 420 Volume Flow Hood is what, exactly?
A volume flow hood called the Testo 420 makes it much easier to measure volume flow at larger air intakes and outlets. Due to the integrated flow straightener that minimizes typical measurement mistakes at swirl exits, it is capable of measuring air flow with great accuracy and efficiency.

By taking out the display and applying the appropriate attachments, you can use the same equipment to measure pressure and Pitot tube data.
Because you can control the system remotely and manage your data using an app on your smartphone or tablet, it is also incredibly practical and intelligent.
Additionally, you may send reports immediately from the field via email and use your mobile device as a second display or remote control.
For applications that call for precise measurement of air flow and pressure at bigger air intakes and vents, including swirl exits, the Testo 420 Volume Flow Hood is ideal.
It can assist you in balancing ventilation systems, checking the effectiveness of heating and cooling systems, finding leaks or blockages in ductwork or pipes, adhering to indoor air quality regulations, and lowering energy usage.
The following are some advantages of using the Testo 420 Volume Flow Hood:
It can accurately and effectively measure airflow.
At swirl outputs, it includes an integrated flow straightener that minimizes typical measurement mistakes.
With the same device, it can measure pressure and Pitot tube measurements.
It may be controlled remotely, and data can be managed using an app on your tablet or smartphone.
Your mobile device may be utilized as a second display or remote control.
It can email reports directly to the site.
It is lighter than 2.9 kg.
The Testo 420 Volume Flow Hood calibrates using the air equivalency method, which involves calibrating the meter with air and then adjusting it using a predetermined correction factor.
Due to the lack of specialized pure process gases or mixed gases, this simplifies the calibration procedure. This could jeopardize the accuracy, though, as it doesn’t take into account fluctuations in gas composition or density.
Volume flow (m3/h) and velocity (m/s) are the two variables used by the Testo 420 Volume Flow Hood to measure air flow. The volume flow measures how much fluid moves through a surface in a particular amount of time.
The rate at which a fluid flows in a specific direction is called its velocity. For evaluating the effectiveness, performance, and safety of ventilation systems, both variables are crucial.
The Testo 420 Volume Flow Hood measures air flow by covering an air intake or vent, such as a swirl exit, with a hood. The measuring accuracy of the hood is enhanced by an integrated flow straightener that lessens turbulence in swirling flows.
Additionally, the hood has an ergonomic grip that makes it simple to put over various outlets.
A measuring device that displays volume flow, velocity, pressure, and other data is linked to the hood. For easier reading or mobility, the measuring tool can be rotated or removed from the hood.
An Ethernet interface on the measuring device enables remote control and data administration using an app on your smartphone or tablet. You can also create reports using the app, add images or comments, and email them from the location.
For various measuring purposes, the Testo 420 Volume Flow Hood includes optionally exchangeable hoods.
For instance, there are hoods of various shapes (round or square), sizes (12 x 12 to 36 x 36 inches), and materials (metal or plastic). For measuring pressure drop across filters or valves, hoods with integrated differential pressure probes are also available.
How Are the Testo 420 Volume Flow Hood and the Epic Hygrometer PCE-WMS 1 Comparable?
Both gadgets are made to make your job easier and faster while assuring excellent quality outcomes, as you can see from their features and advantages.
They do, however, serve various purposes and have various uses. Therefore, taking into account your unique demands and preferences is the best method to compare them.
The following are a few key distinctions between the two devices:
The Testo 420 Volume Flow Hood detects air flow and pressure, while the Epic Hygrometer PCE-WMS 1 measures temperature and humidity.
Up to 100 sensors can be connected to the Epic Hygrometer PCE-WMS 1.
