VTSYIQI Lab Turbidity Meters Turbidimeter Turbidity Meter Tester Kit with 4 PCS Calibration Solution Vials Range 0~1100 NTU/FNU 0~275 EBC 0~9999 ASBC ASTM ISO 7027 Standard

Feature:

★Easy-to-use portable turbidity meter comes with a standard carrying case. 2 to 5 points push-button calibration using the Formazin Standards.

★Selectable 4 turbidity units, including the NTU, FNU, EBC and ASBC. Single measurement mode automatically recognizes and holds the stable reading.

★Continuous measurement mode can be used for indexing or matching the sample vials. Auto-Power Off effectively conserves battery life.

★Setup menu allows setting the 7 parameters, including the number of calibration points, resolution, date and time, etc. Reset feature automatically resumes all settings back to factory default options.

★Expanded memory stores and recalls up to 100 data sets. Stored data can be transferred into computer by USB communication interface. Multi-mode power scheme (battery, power adapter or USB port) ensures that use the meter smoothly.

Portable Turbidimeter Turbidity Meter Kit Turbidity Tester with 2 PCS Glass Sample Vials Range:0~1100 NTU/FNU, 0~275 EBC, 0~9999 ASBC

Introduction:

High performance portable turbidity meter, 2 to 5 points calibration, selectable 4 turbidity units. The meter is suitable for process control and field use.

Unpacking Before unpacking, ensure that the current work environment meet following conditions.

Relative humidity is less than 80%

Ambient temperature is greater than 0C and less than 60C

No potential electromagnetic and ambient light interference

Operating Principles

portable turbidimeter operates on the nephelometric principle of turbidity measurement and is designed to meet the criteria specified in ISO 7027.

The following figure shows basic optical system of the meter. It includes a light source and a detector to monitor the light scattered at 90 degree with respect to the incident beam.
