Relative humidity data-logger RFRHTemp2000A

temperature and humiditywirelessradio frequency

Overview
The RFRHTemp2000A is a wireless temperature and humidity data logger with external humidity and RTD-based temperature sensors, designed for fast response and reliable environmental monitoring. The integrated LCD provides current readings plus minimum, maximum and average statistics. User-programmable alarms can trigger email or text notifications when set thresholds are breached. Compatible with MadgeTech 4 Software for start/stop/download and data presentation in customizable engineering units. MadgeTech Cloud ready for remote monitoring on smartphones, tablets or web-enabled devices. Note: RFC1000 wireless interface required.
