DL7101 - Digital Thermometer

Dual input contact thermometer offering fast and accurate temperature indication. K type single or dual input with differential temperature.


    • Displays maximum reading and data hold.
    • Large backlit LCD
    • T1-T2 mode for differential temperature
    • Accuracy to 0.5 % on °C and °F settings.


SL911 - Compass Inclinometer

The SL911 allows the solar installer to be much more exact with line of sight for roof slopes and heights without the use of a ladder.

This combinational tool has a precision compass and clinometer built into one unit that is excellent for Solar PV, Solar Thermal and surveyors. The casing is a solid one-piece unit equipped with measurement card & special bearings, which are hermetically sealed in a dampening liquid. This helps to prevent shock and allows a quick and accurate measurement.

    • 90° Clinometer for roof angle
    • Percentage increase and decrease to measure building height
    • Compass azimuth with reverse scale to prevent error when survcarry case
    • Adjustable eye pieces

SL801 - Refractometer

The SL801 allows you to measure the Glyco Ethelene content of the solar liquid, thus preventing the system



    • Correcting screw for adjustment of null
    • Adjustable eye piece
    • Supplied with small suction tube
    • Small screw driver to adjust null

pH Meter - Digital pH Meter

The small hand held PH meter enables you to measure the PH level of the fluid in the Solar Thermal system.


    • Correcting screw for adjustment of pH calibration
    • Range from 0.0 to 14.0pH
    • Small screw driver to adjust null
