Hanna HI770 Silica High Range Checker
A digital result for high range silica samples
The HI770 is a dedicated silica colorimeter with a 0–200 ppm range and a 1 ppm display increment. It suits higher concentration water quality and treatment investigations where the expected result is beyond a low range silica test.
Choosing the right measurement
The maximum range and the resolution need to be considered together. For low concentrations in aquarium or source water, the HI705 low range model is a different choice; the HI770 should not be described as a more sensitive replacement. Always compare results using the same reported chemical form and units.

What is included
- HI770 Checker
- Two sample cuvettes with caps
- Starter reagents for 6 tests
- AAA battery and instructions
Reagents and optional accessories
Order HI770-25 for the separate 25-test refill. HI770-11 is the optional instrument check set.
Care and reliable results
Prepare the sample using the HI770 procedure, allow the specified reaction time and wipe each cuvette before measurement. Only use the dedicated reagent refill. The optional calibration check set is for validating the instrument, rather than testing the water sample.

Matching methods and supplies
Match the exact instrument and method. These are separate products; check the supplied contents before adding another item.
- Hanna HI770-11 Silica High Range Checker Verification Set — Reference cuvettes check the matching factory-calibrated Checker; they are not sample reagents and do not provide user calibration.
- Hanna HI770-25 Silica High Range Reagents for HI770, 25 Tests — Match the full instrument code and analytical method. Reagents are separate from the instrument and from verification standards; no substitution by shared parameter name.
Care and method preparation
Cleaning, storage and sample preparation have different roles. Follow the instructions for the exact instrument and method.
- Hanna HI731318 Cuvette Cleaning Cloths, 4 Pack — Cloths and cleaning liquid have separate optical-care roles. This is not an instrument-specific reagent, standard, mandatory extra or supplied-item promise.
- Hanna HI93703-50 Cuvette Cleaning Solution, 230ml — Cloths and cleaning liquid have separate optical-care roles. This is not an instrument-specific reagent, standard, mandatory extra or supplied-item promise.
