This device is a temperature monitor with an alarm output triggered by a certain high or low trigger point. The high and low temperature alarms can be set to any level and can be turned on and off individually. A wide range of temperatures can be measured, and displayed in either degrees Celsius or Farenheit. A small, water-resistant probe is attached to the box by a long 1-metre cable.

Water-Sensor
The owner fastens the ends of two wires in a desired position. Whenever water or a moist material comes into contact with these two wire ends, an LED lights up on the sensor. There is one LED for each channel which indicates the presence of moisture, but does not display the amount of moisture. The sensor must be connected to a 12V power source.
This sensor works by passing a tiny electric current through the water. The current signal is amplified by circuitry in the sensor.
ES-1500 - Panel-mount module, with exposed circuitry on the back side. Screw terminals on the back side are where external wiring (not included) is connected. ES-1502 - Fully enclosed box. 8" wire leads come out of the box.
