Product Details
COLORIMETER PHOTOCHEM AUTO ZERO
- Product ID:
- Category: Photo Electric Instruments
All models are microprocessor based and intelligent units.
The light source is a sealed cluster of LED's of specific wavelengths.The wavelength is choose from the panel controls. Light is focused on a test tube with the solution and onto a photocell. Output from the Photocell is fed to an amplifier and a microprocessor to process thesignal. The microprocessor also controls the wavelength of the LED.
The operation of the unit is very simple. An AUTO ZERO switch sets the full scale of 0.00 OD or 100 % T with blank. Further readings ofstandard & sample are taken as usual.
Mains only, Mains and Battery models are available. Additionally Mains only with four scales of Optical Density, % Transmission and two Concentration scales are available.
