GRS-DC-I/O low-power wireless temperature and humidity measuring point-深圳市格瑞斯通自控设备科技有限公司

GRS-DC-I/O low-power wireless temperature and humidity measuring point

GRS-DC-I/O is a low-power wireless temperature and humidity measurement point. The product adopts the company's unique wireless spread spectrum technology, which not only avoids the problem of excessive power consumption in low-frequency communication bands, but also avoids the problems of short transmission distance and insufficient penetration in ZIGBEE communication. The temperature and humidity acquisition accuracy is higher than the national standard, and the device is equipped with a built-in battery, which can last for more than 3 years on a single charge. The shell adopts IP65 protection level, fully meeting the conditions for outdoor use.

In the implementation of the project, the laying of communication cables, pipelines, and power lines with a large workload is avoided, and users can easily adjust the installation position according to the actual usage situation on site.

GRS-DC-I is a probe built-in measuring point that can be fixed to walls. Simple and convenient installation.

GRS-DC-O is an external probe type single temperature measuring point that can be applied to ultra-low temperature measurement sites, with a minimum measurement of -150 ℃. The probe wire comes standard with 0.6 meters and can be customized for long-distance probe wires, with a maximum length of 20 meters.
