Product Details
Refrigerant (R1234ZE) Leakage Monitoring Sensor KGD - AM - 205
Product Introduction
The refrigerant (R1234ZE) leakage monitoring sensor KGD - AM - 205
is a gas sensor for real-time monitoring of R1234ZE refrigerant
leakage. It adopts the patented technology of Sifang
Optoelectronic's infrared dual-beam, which not only extends the
product's service life but also better solves the impact of
temperature, humidity, and device aging on the measurement accuracy
of the sensor. It has better long-term stability and higher
reliability.
Product Features
- Long service life, up to 15 years.
- Fast response speed, with no false alarms or missed alarms.
- High precision, with high detection accuracy within the full
temperature and humidity range.
- Anti-condensation and high reliability.
- Anti-interference and good gas selectivity.
