Hanna HI97770 Silica High Range Portable Photometer – 0 to 200 mg/L

The Hanna HI97770 is a heavy-duty, waterproof portable photometer designed to measure High Range Silica in industrial water systems. Adapting USEPA Method 370.1, it accurately measures silica concentrations from 0 to 200 mg/L (ppm). Featuring CAL Check™ performance validation and an IP67 casing, it is the standard instrument for managing heavy scaling in HVAC cooling towers, geothermal heating systems, and industrial process water.

Take control of heavy industrial scaling with the Hanna HI97770 Silica High Range Photometer. While high-pressure boilers require ultra-pure water, standard industrial cooling towers and HVAC systems across Pakistan 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.

The HI97770 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 mg/L (ppm). By tracking these levels, plant managers know exactly when to initiate a cooling tower "blowdown" and how to dose their silica-inhibiting chemicals. The meter features a Positive-Locking System, ensuring the glass cuvette locks into the exact same position every time, preventing optical alignment errors in fast-paced factory settings.

Key Features:

• High Range Scale (200 mg/L): Specifically calibrated for measuring heavily concentrated silica in cooling loops and geothermal fluids.
• CAL Check™ Verification: Instantly proves the meter is functioning flawlessly using Hanna's certified, NIST-traceable optical standards.
• LED Light Source: Generates virtually no heat, ensuring electronic stability even during continuous, back-to-back chemical testing.
• IP67 & Floatable: The rugged plastic casing is entirely sealed from dust, dirt, and water, easily surviving the harsh environment of an industrial pump room.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI97770 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 HI97705?

A: The HI97705 is for Low Range (0.00 to 2.00 mg/L), used in RO systems and power plants. The HI97770 is for High Range (0 to 200 mg/L), used in cooling towers and raw groundwater analysis.

Q: Does it have an auto-shutoff?

A: Yes, the meter automatically shuts down after 15 minutes of inactivity to preserve the 800-measurement lifespan of the AA batteries.
