Room Process Monitor
Product Code : CPM 105H
Brand Name : Styrax
Product Description


            The STYRAX “Clean Room Process Monitor” has been specially developed keeping process measurement requirements of CLEAN ROOMS in Pharmaceutical industries. The Process Monitor can measure Relative Humidity, Temperature and Differential Pressure through inbuilt sensors. It has on demand dew point display. The Monitor has status LEDs for process violation indication.  Humidity, Temperature and pressure will display individually and data transfers to any master device on modbus serial communication. It also has communication diagnosis LED. The monitor has inbuilt buzzer for audible process violation. It has keypad to programming the instrument by user. It has Stainless steel Modular Face plate, which is designed as a mounting accessory for monitor suited for Modular wall Clean Room applications where you need flush mounting mechanism. This instrument enables you to measure humidity, temperature and differential pressure in the following fields:

·         HVAC (Heating, ventilation, Air conditioning, cooling)
