NEW – Clean Room Monitor – Series CR3

clean room monitor

What is a Clean Room Monitor ?

A Clean Room Monitor, monitors a confined space, such as pharmaceutical labs and hospital isolation units, where provisions are made to reduce the particulate contamination and control environmental parameters like humidity, temperature and pressure within specifed limits to achieve a controlled environment for sensitive processes. Generally, the environment is controlled through the controls of an HVAC system, however due to the sensitive nature of cleanroom activities, facility management teams are seeking a solution that enables them to monitor these spaces not only within the space but also remotely.


The CR3 Series Clean Room Monitor, was developed specifically to allow for monitoring of confined spaces with accuracy and reliability. The CR3 allows for either in-room or remote monitoring with three different models; integrated sensors, remote sensors or display only to suit a variety of installation needs. It features a flush fitting stainless-steel front plate that enables the user to wipe-down the unit when necessary.

The CR3 allows for more effcient measurement of three critical parameters; humidity, temperature and pressure, in one flush mount enclosure. It is equipped with sensors with best in class accuracies to match cleanroom requirements, and can communicate with the building automation system via Modbus, BACnet® or Analog outputs. It is powered by a standard 24 Vdc or 24 Vac power supply.

The CR3 features a visual display for each parameter with bright, easy-to-read LED’s, which enable users to view from long distances. Each parameter includes an alarm function with programmable setpoints for different application types, and provides both high and low alarm visual indication.


The CR3 is CE and RoHS compliant.

NEW – Dew point Transmitter – DP Series

Dew point

Dew point (Td) – is increasingly being used as a moisture measurement & control parameter for two reasons:

1/ Dew Point is a direct measure of only the moisture content in the air, unlike the measure of relative humidity that is a hybrid measurement of temperature and moisture.

2/ The dew point is an accurate predictive value that indicates the temperature at which moisture will condense out of the air. Liquid moisture condensing on surfaces can cause staining, creates a ideal environment for mold growth and left unabated can result in structural deterioration of many building components.

Moisture control in buildings is becoming a critical issue particularly when buildings are becoming more energy efficient by adding insulation, utilizing thermal pane windows and utilizing much more efficient cooling equipment. All of these initiatives reduce the sensible load (dry bulb) in buildings meaning that cooling equipment runs for shorter periods of time to cool the space to the target temperature.

At the same time, moisture loads (or latent loads) in the space contributed by outside air ventilation, people and some indoor activities have not been affected by these energy initiatives. As air conditioners run less frequently, the ability to remove and control moisture in the space is also diminished. In many buildings we are at the point where we cannot depend on temperature sensing to control moisture. It is now necessary to separately measure moisture and in some cases employ specific dehumidification strategies to control it.

Precision Dewpoint Transmitters

It’s state-of-the-art design combines digital linearization and temperature compensation with a highly accurate and reliable thermoset polymer based capacitance humidity sensor and curve-matched NTC thermistor temperature sensor for reliability and accuracy in the most critical applications.

Dewpoint Transmitters

The DEW POINT sensors are available in room, duct or outside mounting configurations to meet the widest range HVAC applications. The DP Series has four measurement variables which include dewpoint, dry-bulb temperature, wet-bulb temperature and enthalpy. Outputs are available by either an analog, BACnet® or Modbus signal to provide the most efficient monitoring and control solution.

Clark Sonic DN-EM KW/Energy Flow Monitor

The DN-EM is an economical energy flow monitor intended for applications in energy transfer and heating/ cooling systems where energy use requires measurement. Energy Monitoring of Heating or Cooling Systems, 1/2” & 3/4” Pipe.

The DN-EM internally calculates the energy passing through the system. The energy used is calculated based on the the mass volume of liquid passing through the system and the difference in temperature between the supply and return lines. The volume of liquid is measured by means of a pulse generating Clark vortex flow transmitter. A RTD sensor built into the flowmeter (T1) measures temperature at the meter and the remote temperature (T2) is measured by means of a precision RTD sensor mounted in a pipe tee.

A scaled pulse output is provided and can be configured to report volume flow rate, mass flow rate or energy total. Modbus 485 communications provides an interface with a building automation or monitoring system.

The unit contains non-volatile memory that records flow and energy, and is updated every ten minutes. However, when flow, mass or energy totals are read, the reported values are true current values; the last stored value is added to the current accumulated value when the applicable register is read.

The default medium for the DN-EM is water. Other media consisting of water and a certain percentage of glycol up to 30% can be field configured.
