Temperature, RH, DP and Clock Indicators:

Description :

The STYRAX “Clean Room Process Scanner” has been specially developed keeping process measurement requirements of CLEAN ROOMS in Pharmaceutical industries. The Process Scanner can measure Temperature, RH Inbuilt integral Sensor, Differential Pressure Inbuilt sensor or three analog inputs or two analog inputs and inbuilt differential pressure sensor. It has on demand dew point display. The Clean Room Process Scanner displays Real Time Clock synchronized with GPS/Server based master clock interfaced through RS485. The Scanner has status LEDs for process violation indication. RH, Temperature and Differential pressure will display individually and data transfers to any master device on MODBUS RTU RS-485 communication. It also has individual communication diagnosis LED's for SCADA communication and Master Clock communication. The Scanner has inbuilt buzzer for audible process violation. It has keypad to program and calibrate the instrument by user. It has Stainless steel Modular Face plate, which is designed as a mounting accessory for monitor suited for Brick and Modular wall for Clean Room applications where you need flush mounting mechanism.
