The Hanna Phosphate Ultra Low Range (0.00 to 0.90 ppm) Checker bridges the gap between simple chemical test kits and professional instrumentation. Chemical test kits have limited accuracy and resolution since they rely upon the human eye to discern differences in color. Professional instrumentation incorporates a light source such as an LED or tungsten lamp with a filter and a light-sensing detector to precisely determine ion concentration.
Hanna Checker | Phosphate ULR
DescriptionProfessional instrumentation offers greater resolution and accuracy but can cost hundreds of dollars. The Hanna Phosphate Ultra Low-Range Checker® uses a fixed wavelength LED and silicon photo detector to provide the accuracy of professional instrumentation at the affordable price of a chemical test kit.
- Compact, Portable Design
- Built-in Timer
- One-Button Operation
The HI-774 Checker HC (Handheld Colorimeter) provides a simple, accurate and cost-effective way to measure phosphate in marine systems including coral reef tanks. Phosphate is an important parameter to measure in aquaculture and aquariums; levels that are too high can lead to extensive algae growth, depleted dissolved oxygen levels, and ultimately can be fatal to many types of fish and aquatic life. Designed as a more accurate alternative to chemical test kits, the HI-774 provides quick, accurate results.
For those that would like measure phosphate as phosphorous we offer the HI-736 Phosphorous Checker HC. Alternatively, to determine the fraction of phosphorous (PO4-P) there is in phosphate (PO43-) the phosphate reading is multiplied by 0.3261. A 0.50 ppm phosphate reading is equal to 0.163 ppm or 163 ppb phosphorous.
Pre-mixed Chemistry
Reagents are pre-measured packets that are added to the sample to take a reading.
Colorimetric Readings
Using an LED at a specific wavelength and silicon photo detector the HI-774 can perform a precise reading of the colour change in the sample based on the phosphate concentration.
Checker HC Calibration Standards
The HI-774-11 CAL-Check standards can be purchased separately and are used to check the performance of the meter to ensure confidence that the meter is working properly.
Automatic Shut-off
The meter is programmed to turn off after seven minutes of non-use or two minutes after taking a reading.
Long Battery Life
The phosphate ULR Checker has an exceptional battery life with a fresh battery lasting for a minimum of 5000 measurements.
Plastic Carrying Case
The HI-774 is supplied complete with meter and reagents for 10 tests that are packaged in a durable plastic carrying case.
Economical
Laboratory grade measurements at a cost of a chemical test kit.
