HI97735C เป็นโฟโตมิเตอร์แบบพกพาขั้นสูงสำหรับการวัดความกระด้างรวมในน้ำได้ถึง 750 มก./ลิตร (ppm) มิเตอร์นี้มีระบบออพติคอลที่เหนือกว่าซึ่งใช้ตัวตรวจจับอ้างอิงและตัวกรองสัญญาณรบกวนย่านความถี่แคบเพื่อการวัดที่รวดเร็วและทำซ้ำได้

• ไม่ต้องอุ่นเครื่องก่อนทำการวัด
• โหมดการสอนสำหรับคำแนะนำทีละขั้นตอน
• ตรวจสอบ CAL เพื่อการตรวจสอบและสอบเทียบประสิทธิภาพ

HI97735C is an advanced portable photometer for the measurement of total hardness in water up to 750 mg/L (ppm). This meter has a superior optical system that utilizes a reference detector and narrow band interference filters for extremely fast and repeatable measurements.

• No warm up time before taking a measurement
• Tutorial mode for step-by-step instructions
• CAL Check for performance verification and calibration

By passing through various layers of soil and rocks, rain water dissolves some mineral substances. Total harness is indicative of the presence of calcium and magnesium in water. High levels of hardness can cause scaling reducing the efficiency of heat transfer in cooling towers. Hardness also increases the consumption of soaps and detergents in industrial washing machines or laundries. The HI97735 uses an adaptation of EPA recommended method 130.1. When the reagent is added to a sample containing magnesium and calcium, the sample will turn a red-violet hue; the greater the concentration, the deeper the color.

The HI97735C has an innovative optical system that offers superior performance in accuracy, repeatability, and the short amount of time it takes to perform a measurement. This compact, waterproof meter is extremely user friendly with a tutorial mode that walks the user graphically, step by step, in performing a measurement. The use of a backlit dot matrix LED allows the use of virtual keys which makes the operation of the meter very intuitive including selecting different units of measure, reviewing GLP data, recalling the last 50 measurements, and customizing the meter to user preferences.

HI97735C is completely waterproof including the cuvette holder that is designed with ridges to protect the optical path from getting scratched by the cuvette and a gasketed battery compartment that holds three common AA batteries. The compact design fits comfortable in the hand for use in the field or on a table for benchtop use. The LCD is 71 mm (2.75″) by 37 mm (1.6″) and is backlit for easy viewing under all conditions.

• LED that generates very little heat
• 8 nm narrowband interference filter that is accurate to +/- 1 nm and offers 25% increase in light efficiency.
• Reference detector that modulates the voltage to LED for consistent light output.
• A concave focusing lens that reduces errors from imperfections in the cuvette
