The HANNA HI 721 Checker®HC bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits are not very accurate and only give 5 to 10 points resolution while professional instrumentation can cost hundreds of dollars and can be time consuming to calibrate and maintain. The HANNA HI 721 Checker®HC is accurate and affordable with immediate results.
The new HI 721 Checker®HC portable handheld colorimeter features a resolution of 0.01 ppm (500 points) and ±0.04 ppm ±2% of reading accuracy. The HI 721 Checker®HC uses an adaptation of Standard Method 315 B.
The contoured style of this Checker®HC fits in your palm and pocket perfectly and the large LCD is easy to read. The auto shut-off feature assures the battery life will not be drained if you forget to turn it off.
The HI 721 Checker®HC is extremely simple to use. First, zero the instrument with your water sample. Next, add the reagent. Last, place the vial into the HI 721 Checker®HC, press the button and read the results. It’s that easy.
The compact TB 210 IR (formerly the TurbiCheck infrared) turbidity meter is designed to allow fast, precise on site or laboratory measurements. The unit measures scattered light at 90 ° angle as stipulated in ISO 7027.
Measuring in the range 0-1100 NTU, the unit is suitable for various applications including drinking water, waste water, process and pool water testing. The infrared light source allows for measurement of coloured and colourless samples.
A simple keypad layout and range selection button ensures further ease of use. Up to 16 results can be stored and reviewed with time and date. The instrument is supplied in a robust carry case with all necessary accessories, and a set of calibration standards.
