Soil/Water Temperature Sensors

Installation Procedure for QMT103/

QMT110

The QMT103/QMT110 sensor has the cable with the connector. The

length of the cable defines the maximum distance from the logger. You

can install the sensor either in soil or in water.

1. Choose a desired location for the sensor. Assure that the sensor is

located within cable length of the logger enclosure.

2. To install the sensor in the soil:

a. Make a hole with a shovel to a depth a little deeper than

desired installation depth of the sensor.

b. To get good sensor contact with the soil, position the sensor

horizontally into the hole and push the sensor into the wall of

the hole to the desired depth until set firmly.

c. Fill the hole with the digged soil.

d. Connect the cable to the logger enclosure.

3. To install the sensor in water:

a. Make a solid base for the sensor to the desired installation

depth in water.

b. Position the sensor firmly to the base.

c. Connect the cable to the logger enclosure.

Installation Procedure for QMT107

During a typical installation, the QMT107 sensor is pressed into pre-

formed holes, but it can also be placed into excavated hole that is then

filled. On hard or rocky ground, a pilot hole is pre-formed with an auger

rod.
