About This Product

■Latest spectrophotometer series

HI 97761 and HI 97762 are portable digital residual chlorine meters for ultra-low concentrations. HI 97761 measures total chlorine in the range of 0.000 to 0.500 mg/L, and HI 97762 measures free chlorine in the range of 0.000 to 0.500 mg/L. It is suitable for checking that there is no (or very little) chlorine in it, and is used to check medical water for dialysis and water purification equipment. The measurement uses a DPD reagent specified by the official method and is highly reliable. Furthermore, numerical verification and calibration of the main unit can be performed using a validator (standard solution set). This ensures high accuracy and reliability. The performance has improved as shown below. - Advanced optical system with beam splitter improves reproducibility and stability. - Light source changed from conventional tungsten lamp to LED. Demonstrates excellent performance. - Navigation function for measurement procedures. ・The waterproof function of the main case has been improved to IP67. (The glass cell insertion part is also more waterproof) ・Automatic logging function for 50 data. ・The remaining battery power (%) is always displayed on the screen. ・Time can be set. (year, month, day and time) - Comes with a backlight function for easier viewing.

■Applications

Management of dialysis water, measurement of residual chlorine in ion-exchanged water, analysis of seawater, measurement of residual chlorine in test water, etc. to determine when to replace water purifier filters, etc. Set contents
