MSA PrimaX I Gas Transmitter

Description of MSA PrimaX I

The transmitter detects toxic gases and oxygen and is housed in an antistatic, reinforced nylon enclosure. It also has a large, easy-to-read LCD screen and attaches to an integral mounting plate for easy installation, while the built-in keypad makes for quick, simple calibration. To transmit data, the unit uses a 4-20 mA output signal and can also be configured to use HART digital communication. With easily replaced plug-in sensors, the PrimaX I transmitter is suitable for laboratories, chemical plants, power plants and several other industry settings.
