About This Product
■Latest spectrophotometer series
The HI 97745 is a portable digital residual chlorine meter that measures low concentrations of free and total chlorine, as well as pH, iron (low concentrations), and total hardness (very low concentrations). In addition to tap water, well water, pools/baths, building management, etc., it is also used to check that chlorine is as low as possible in industrial wastewater.
This instrument also allows numerical verification and calibration of the main unit using a validator (standard solution set). This ensures high accuracy and reliability.
This device is a powered-up model of the conventional HI 96745, and its performance has been 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.
