Product Description
Turbidity and Free/Total Chlorine Portable Meter with CAL CHECK Technology, EPA Compliant. The HI 93414 measures the most important parameters of drinking water: turbidity and free/total chlorine. Designed for water quality measurements, HI 93414 provides reliable and accurate readings on low turbidity and chlorine values. The HI 93414 meets and exceeds the requirements of USEPA and Standard Methods both for turbidity and colorimetric measurements. This instrument incorporates an optical system which guarantees accurate results. The optical system, consisting of a tungsten filament lamp, three detectors (scattered, transmitted for turbidity meter range and one for colorimeter range), and a narrow band interference filter at 525 nm assures long term stability and minimizes stray light and color interferences. It also compensates for variations in intensity of the lamp, making no need for frequent calibration. The 25 mm round cuvettes made from special optical glass guarantee repeatability and consistency of measurements.Accurate Nephelometric MeasurementUtilizing the nephelometric principle, this turbidity meter ensures dependable and accurate readings by detecting scattered light from suspended particles in water samples. The high intensity LED light source enhances measurement reliability, making it well-suited for laboratory analyses of water quality. With a measurement range of 0-1000 NTU and a resolution of 1 NTU, it provides users with precise data for regulatory and research needs.
Simple and Efficient CalibrationCalibration is straightforward using the standard formazin solutions. The auto zero and direct reading features, along with knob and push-button controls, facilitate quick setup for accurate measurements. This efficient process ensures consistent and repeatable results, meeting laboratory and industrial compliance requirements as per ISI and ISO 7027 standards.
Robust Design for Laboratory UseBuilt with a durable ABS plastic body, this meter is lightweight at 34 kg, portable, and designed in a compact, rectangular shape (305 x 210 x 95 mm). Its resistance to temperatures up to 50C and the inclusion of specific glass cuvettes make it adaptable for extensive laboratory use across varying environmental conditions.
