Hanna Instruments has released a new phosphate calorimeter, and it’s small and very affordable. This tiny device weighs only 2.3 ounces and is priced right at $49.50. It’s small size, cheap price, and ease of use will take away any excuses reefkeepers had for not checking their phosphate levels.
Here are a few specifications:
- Model: HI 713
- Free Phosphate Range: 0.00 to 2.50 ppm(mg/L)
- Accuracy of +/- .04 ppm, +/- 4% of reading @ 25C
- 0.01 ppm resolution (250 points)
- Auto-shutoff to preserve battery life
- 10ml glass cuvettes
Here’s the description on the Hanna Instruments website:

ACCURATE AND AFFORDABLE CHLORINE 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.
