HBD5w series  Portable Water Analyzer

Advanced instrumental features include calibration edit, and temperature -compensated ISE measurement. Use calibration edit to review, delete or re-measure calibration standards.

The HBD4WMS Handheld instruments have user-fixed configuration of multi single probes, and offer temperature compensation. HBD5WMP Handheld instruments have capability to test multi-parameters with single probe replaceable, and offer temperature compensation as well.  

General parameters include Turbidity, SCT, DO, pH, Ca2+, Mg2+, Cl2, ClO2, Cl-,F-.NO3-,NH3+,CO2/CO32-, BF4-,K+,Na+ … .

Typical applicable in plant boiler water, ultra pure water, industrial water analyzing.

Ease of operation, data display and retrieval, and advanced analytical techniques for performing sophisticated analyses make the HBD4/5w the best choice for the multi-user lab and research chemist, as well to field patrol.

4620 LIF Chlorophyll / Algae Detector 

This small transducer is completely an intelligent analyzer with advanced property to be used in line, to be used for the indirect monitoring and detection of indicator pollutants, including phosphorus and nitrogen. Chlorophyll system consists of a probe similar in concept to the field-type fluorometers but much smaller. The output of the chlorophyll sensor is automatically processed via the RS485 or 0-20mA to provide readings in either generic fluorescence units (percent full scale; % FS) or ug/L of chlorophyll in the station. No pump is required for the system.
