Hanna HI83141-1 | Portable Analog pH/mV/Temperature Meter

Experience the reliability of a classic design with the Hanna HI83141-1, a rugged Portable pH/mV/Temperature Meter that prioritizes simplicity and stability. While modern meters often rely on complex digital menus, the HI83141 remains a favorite among university professors, field researchers, and industrial technicians in Pakistan because it uses Manual Calibration Trimmers (knobs) on the front panel. This allows for intuitive, instant adjustment without navigating software settings.

The HI83141 is engineered to perform in difficult environments. It uses a Pre-Amplified pH Electrode (HI1230B) with a built-in temperature sensor. Standard pH signals are weak and high-impedance, making them susceptible to interference from humidity, electrical noise (like pumps), or long cables. The pre-amplifier strengthens the signal before it leaves the probe, ensuring your readings remain stable and accurate even in damp greenhouses or noisy industrial plants.

In addition to pH, this meter features a mV (Millivolt) Mode, allowing you to measure ORP (Oxidation Reduction Potential) using an optional ORP probe—a critical feature for monitoring disinfection in swimming pools and water treatment facilities.

Key Features of the Product

• Manual "Analog" Calibration: Features two dedicated knobs (Slope and Offset) for calibration. This allows users to manually tune the meter to the buffer solution, offering a level of control and "feel" that push-button digital meters cannot match.
• Pre-Amplified Probe Input: The included DIN connector is designed for pre-amplified electrodes. This technology eliminates the "drift" caused by electrical noise and high humidity, making it far superior to standard BNC meters in field conditions.
• 3-in-1 Measurement: A versatile tool that measures pH, mV (ORP), and Temperature (°C), covering all the bases for water quality analysis.
• Automatic Temperature Compensation (ATC): The probe includes a built-in temperature sensor, ensuring that pH readings are automatically corrected for the temperature of the sample.
• Low Battery Indicator: A dedicated LED lights up when the battery is low, preventing the risk of taking erroneous readings due to insufficient power.
• Rugged Construction: The heavy-duty ABS plastic case is built to withstand drops and rough handling on the job site.

Frequently Asked Questions (FAQs)

Q: Why choose manual calibration over digital?

A: Simplicity and Troubleshooting. With manual knobs, you can physically see how much you are adjusting the meter. It is excellent for teaching students the principles of pH calibration (Slope vs. Offset) and is often faster than scrolling through digital menus.

Q: What is the "mV" mode for?

A: The mV (Millivolt) mode is primarily used for ORP (Oxidation Reduction Potential) measurements. By attaching an optional ORP probe, you can test the effectiveness of chlorine or ozone in water. It can also be used to check the health (slope) of your pH electrode.

Q: Does this meter come with a probe?

A: Yes, the HI83141-1 kit typically includes the HI1230B plastic body pH electrode (with built-in temperature sensor and DIN connector), calibration screwdriver, and starter solutions.

Q: Can I use any BNC probe with this?

A: No. This meter uses a DIN connector specifically for pre-amplified probes. This is a deliberate design choice to ensure higher stability and noise immunity. You must use Hanna DIN probes (like HI1230B).

Q: Is it waterproof?

A: It is water-resistant (splashes won't hurt it), but it is not fully waterproof (IP67) like the HI991001. Do not submerge the meter body in a tank.
