Instrument characteristics
TECHNICAL INDEXMicro TOL online turbidity meter parameters:
Measurement principle:
90°WLScattered light method
The measurement adopts the standardized 90 ° scattered light method in accordance with USEPA180.1.
The turbidity of the medium is determined by the intensity of scattered light. The white light beam is scattered by solid particles in the medium, and the scattered light is detected by a scattered light detection unit arranged at a 90 ° angle to the white light source.
90°NIRScattered light method
The measurement adopts the standardized 90 ° scattered light method in accordance with ISO7027/EN27027. The turbidity of the medium is determined by the intensity of scattered light. Near infrared light of a certain wavelength is scattered by solid particles in the medium, and scattered light is detected by a scattered light detection unit arranged at a 90 ° angle to the infrared light source.
function
IROr white light measurement
Infrared type can be selected to meet the design standards of ISO7027 and DIN27027. The white light type meets the design standards of USEPA180.1 for turbidity measurement. Both models have long-lasting light sources.
BacklightLCD
Backlit LCD ensures clear display in dark conditions. Backlight is suitable for continuous operation. The brightness can be adjusted in the menu.
Water vapor elimination
MicroTOL is equipped with a continuous water vapor elimination system. The replaceable drying bag is installed under the instrument panel for drying the air. The system heat is used to heat the air, and the fan inside the instrument circulates the heated air around the sample cell, eliminating the process of drying the sample cell.
call the police
Provide 2 independent, programmable alarm relays.
ultrasonic cleaning
This option is used for continuous cleaning of the sample tank. It cannot completely replace manual cleaning, but this system will greatly extend the cleaning cycle. Attention: The system requires the use of a special sample pool.
correct
The optional calibration kit is a completely sealed test tube, similar to laboratory calibration steps. This dry calibration method is very fast, clean, and reusable. The menu on the screen will guide you to quickly and easily calibrate.
