Hanna Instruments has released a new phosphate checker colorimeter that should make it easier for you to check your water parameters or at least phosphate. The new phosphate colorimeter has a resolution of 0.01 ppm (250 points) and 4% ±0.04 accuracy of reading. And requires the use of the Hanna reagent that is included. The colorimeter is very affordable with a $40 MSRP assigned to it which tell us that Hanna wants to get it in the hands of more then just the dedicated hobbyists but common folk as well. Did we mention that it works with saltwater? Yes. It does. Having a $40 PO4 colorimeter is great but we would like to see more affordable colorimeters (that work with saltwater) appear on the market including all of our common water parameters. You listening Hanna?

ACCURATE AND AFFORDABLE PHOSPHATE MEASUREMENT
Orthophosphates are found in natural and waste waters. They are commonly added to drinking water as a corrosion inhibitor. The instantaneous analysis of orthophosphate by colorimetric determination provides rapid results using a standard analysis technique. The HANNA HI 713 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 713 Checker®HC is accurate and affordable. The HI 713 Checker®HC portable handheld colorimeter features a resolution of 0.01 ppm (250 points) and 4% ±0.04 accuracy of reading. The HI 713 Checker® HC uses an adaptation of Standard Method 4500-P E. 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 713 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 713 Checker®HC, press the button and read the results. It’s that easy.
