Professional Light Meters
DT-8808/8809A light meters provide accurate display light levels in terms of Foot Candles (FC) or LUX over a wide range. Just turn the Function Switch to select the “lux” scale and set the range to desired range, then remove the photo detector to the light source in a horizontal position and read the illuminance nominal from the LCD. When the measurement is completed, replace the photodetector from the light source.

Carbon Monoxide Meters
CO-180/181 Carbon Monoxide Meter detects the presence of carbon monoxide (CO) and measures concentrations between 1-1000 parts per million (PPM). The Meter indicates the presence of CO by a reading on the LCD and a beeper tone. The beeper function much like clicking of a Geiger counter: Above 200 PPM, the beeper sounds continuously with the concentration of CO. From 35 PPM to 200 PPM, the beeper sounds discontinuously with the concentration of CO.

Earth Ground Resistance Testers
Electronic Digital Earth Resistance Tester is a direct replacement of the conventional hand generator type tester. It is designed for the measurement of the resistance of earthing used in the electrical equipment as well as for the measurement of ground resistivity. It can be used for measurements of the other low regular and liquid resistances. It can also be used for the measurement of voltage AC, voltage DC, and resistance.
This instrument has wide applications for testing earthing installation in power-based industries, telecommunication networks electrical traction systems, etc.
