Conventional heat detector

Product
Overview

　　OT303
Heat Detector is designed to timely and automatically detect and judge
on-site fire factors. With a precise NTC resistor, it can sense the
environment temperature. It also can automatically realize
contamination compensation of non –fire factors (like temperature,
humidity, dust, etc.) and effectively keep detector in a steady status.
