Hanna HI770 Silica High Range Checker® HC – 0 to 200 ppm

The Hanna HI770 Checker® HC is an advanced, pocket-sized digital colorimeter designed to measure High Range Silica in industrial water systems. Adapting USEPA Method 370.1, it accurately measures massive silica concentrations from 0 to 200 ppm (mg/L). It completely replaces subjective chemical test strips, acting as the standard diagnostic instrument for managing heavy scaling in HVAC cooling towers, geothermal heating systems, and industrial process water.

Take absolute control of heavy industrial scaling with the Hanna HI770 Silica High Range Checker® HC. In Pakistan, standard industrial cooling towers and massive textile HVAC systems operate with raw groundwater. This water is naturally rich in silica, which concentrates heavily as the cooling water evaporates. If the silica level is not strictly monitored, it precipitates out as a thick, thermally insulating scale that destroys heat exchanger efficiency and ruptures pipes.

The HI770 is explicitly designed for these heavy-mineral environments. Operating on the USEPA Method 370.1, it measures massive silica concentrations ranging from 0 to 200 ppm (mg/L). By tracking these levels digitally, plant managers know exactly when to initiate a cooling tower "blowdown" and how to dose their silica-inhibiting chemicals. It brings benchtop accuracy to the palm of your hand, completely eliminating the guesswork of reading faded chemical test strips.

Key Features:

• High Range Scale (200 ppm): Specifically calibrated for measuring heavily concentrated silica in cooling loops and geothermal fluids.
• Digital Accuracy: Removes the danger of misinterpreting liquid color-drop kits when handling critical scaling metrics.
• Cost-Effective QA: Provides elite, narrow-band optical technology at the price of a standard field test kit.
• Compact & Rugged: Designed to be carried in a lab coat pocket directly into active industrial pump rooms.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI770 in Pakistan?

A: Check Kamadi.pk for competitive B2B rates. We support commercial maintenance teams with officially certified Hanna diagnostic tools.

Q: How does this differ from the HI705?

A: The HI705 is for Low Range (0.00 to 2.00 ppm), used strictly in ultra-pure RO systems and power plants. The HI770 is for High Range (0 to 200 ppm), used in cooling towers and raw groundwater analysis.

Q: Are the required reagents included?

A: Yes, the checker comes with a starter kit of reagents. Replacement reagents (HI770-25) are readily available.
