Hanna HI8734 | Portable Multi-Range TDS Meter (Manual Temp. Comp)

Ensure the purity of your industrial water systems with the Hanna HI8734, a heavy-duty Portable TDS Meter designed for the rigorous demands of water conditioning professionals in Pakistan. While standard "pen-style" TDS testers are limited to light duty applications, the HI8734 is engineered for high-stakes environments like boiler feed water, cooling tower bleed-off, reverse osmosis (RO) verification, and demineralization plants.

The HI8734 distinguishes itself with its 3-Range Capability, allowing you to measure from very low concentrations (0.0 mg/L) up to high concentrations (19.99 g/L) with a single instrument. It utilizes the specialized HI76301D Four-Ring Potentiometric Probe, which offers superior linearity and resistance to clogging compared to traditional amperometric (2-pin) probes that fail in high-mineral water.

Unlike the HI8733 (which uses Automatic Temperature Compensation), the HI8734 features Manual Temperature Compensation (MTC). This allows operators to manually set the temperature coefficient using a front-panel knob, a preferred method in strictly controlled SOPs where temperature values are fixed or independently verified. With a fixed TDS factor of 0.5, it provides consistent, industry-standard readings for salt-based solutions.

Key Features of the Product

• 3-in-1 Multi-Range System: Seamlessly switch between three measurement ranges (0.0 mg/L to 19.99 g/L) to accurately test everything from RO permeate to brackish well water.
• Robust 4-Ring Probe (HI76301D): The included PVC-body probe uses four stainless steel rings to drive and read the signal, eliminating the "polarization effect" (false low readings) common in high-TDS samples.
• Manual Temperature Compensation (MTC): A dedicated knob allows you to manually input the sample temperature from 0 to 50°C, ensuring accuracy even if the probe takes time to equilibrate.
• One-Point Manual Calibration: Features a large calibration trimmer on the front panel, allowing for quick, tool-free adjustments against standard TDS solutions (like HI7032L).
• Rugged Field Design: Built for the factory floor, the meter casing is durable and simple to operate, with clear range buttons that eliminate the confusion of complex digital menus.

Frequently Asked Questions (FAQs)

Q: What is the price of the Hanna HI8734 in Pakistan?

A: Prices for imported industrial meters fluctuate with the exchange rate. For the most current price and stock status, please contact Kamadi Pakistan. We are the authorized distributor and ensure you receive genuine probes and valid warranty cards.

Q: Why does this meter use Manual Temperature Compensation (MTC) instead of ATC?

A: MTC gives the user total control. In some specific industrial protocols, technicians are required to measure temperature with a certified glass thermometer and input that value manually to eliminate any potential error from an electronic temperature sensor drift.

Q: Can I use the HI8734 for testing drinking water quality?

A: Yes, absolutely. Range 2 (0 to 1999 mg/L) covers the standard drinking water TDS range perfectly. However, for drinking water, many users prefer the simpler Hanna HI98301 (DiST 1) pocket tester. The HI8734 is better suited for industrial plants managing large volumes of water.

Q: What calibration solution should I use?

A: It depends on your measuring range. For most general applications, we recommend HI7032L (1382 ppm). If you are measuring high-salinity water, use HI7036L (12.41 ppt).

Q: Does the probe need to be replaced often?

A: The HI76301D is a very durable 4-ring probe that resists fouling. With proper cleaning (using HI7061L cleaning solution) and storage, it can last for several years, unlike glass pH electrodes which degrade faster.
