Overview
The SAFETAK GC90S-NH3 (100ppm) Single-point Wall-Mounted Gas Monitoring Alarm is a monitoring device for the detection of ammonia (NH3) in non-explosion-proof environments. It is directly powered by a 220V AC power supply, has a corrosion-resistant die-cast aluminum housing with IP66 High Protection Rating, and can be connected to a Miscellaneous control linkage via an optional relay signal output.
Features
1. Ultra-high Protection Rating: IP66 protection, good waterproof and dustproof performance, die-cast aluminum shell corrosion resistance, with strong electromagnetic Shielding performance.
2. High product mass: Sensor adopts international good brand, high detection accuracy and short reaction time.
3. High-intensity, diverse alarm system: with up to 120dB acoustic alarm and 360 ° high-intensity light alarm, it is clearly visible at a distance.
4. Two display modes are available: LCD and LED.
5. Humanized design: Maintain the menu password lock to prevent misoperation; optional relay signal output can be connected to other control linkage devices.
Principle
Sensors based on electrochemistry are used to continuously detect the target gas. When the ammonia concentration in the environment reaches a preset low alarm point (25ppm) or high alarm point (50ppm), the device will trigger sound and light alarms and output corresponding control signals.
Applications
Petroleum, petrochemical, metallurgical and other industrial sites of non-explosion-proof places, gas stations, boiler rooms, laboratories, Food processing and other sites and office environments.
Standards
In line with the national standard of GB12358-2006 "General technical requirements for working environment Gas detection alarm instrument", and obtained the type approval certificate of Measurement instrument.
Steps
1. Install the equipment at the target monitoring location.
2. Connect the 220V AC power supply.
3. After the equipment is powered on, it enters the working state and starts to continuously detect the gas concentration.
4. Relevant settings can be made through the maintenance menu (password required).
5. For linkage control, connect the optional relay signal output to the Miscellaneous equipment.
Notice
