Photo Colorimeter

Photo Colorimeters are microprocessor based digital colorimeters and combine ease of use with high testing capability. These photo colorimeter systems are durable, dustproof, waterproof, compact and designed keeping in mind the users' experience in laboratory and field. Due to user friendly features and ease of use these equipment are used widely for blood and chemical analysis.


Standard glass filters 8 and 5 1ml sample is sufficient for testing
Dust and waterproof housing Soft touch Keypad
Optional RS232 interface CE and ISO certified
Highly stable and accurate Optional Battery operation

Our digital colorimeter equipment are durably constructed ensuring safe working even in tough conditions. These colorimeters require low maintenance and let the users experience long years of worry free working. Small and compact design makes these units easy to handle both in laboratory and field.

Depending upon your testing needs these units are designed with both 8 and 5 filters models.

With these systems you get four different outputs through LCD display including % Transmission (%T), Absorbance (Abs), Concentration (Conc) and K Factor.

Our Photo Colorimeters feature in-built memory to retain last "K" factor for concentration even after power loss.

Branded and high quality standard glass filters are used in these units that cover a wide range of 400 to 700 nm in order to obtain extremely good results.

The filter setting in colorimeter is controlled by a rotating disc having 8 or 5 filters. An automatic shutter is used to stop the light reaching the photocell, when test tube is not inserted in the tube holder.

These meters are operated through 110 / 220 volts power supply however battery operated power supply can also be added as optional.
