HI98115
-
GroLine pH Meter [High Resolution]
-
Measuring range: 0.00 to 14.00 pH, Accuracy: ±0.2 pH;
-
Suitable for field or laboratory use, simple and affordable operation, compliant with laboratory measurement standards.
-
Features a large LCD screen, automatic calibration recognition, measurement value identification, electrode diagnostics, auto power-off, and stable endpoint measurement indicator. During measurement, the screen will display an hourglass icon. Once the reading stabilizes, the hourglass icon disappears and the reading can be taken. The pH electrode diagnostic function automatically diagnoses the pH electrode status during calibration. When the Err error message appears on the display, it indicates that the pH electrode needs cleaning or has been damaged. Battery level display and auto power-off: when battery power is low, a low battery indicator appears, prompting timely battery replacement. The instrument can be set to auto power-off in 8 minutes, 60 minutes, or disabled. It is ideal for rapid pH measurement of micro-volume samples or small-neck samples, and can replace pH test strips.
Large LCD Display Function
New appearance and display design, large font display of readings and stability indicator, low battery alert with fast response;
Automatic Calibration Recognition Function
Automatically recognizes pH standard solutions, automatic 1-point or 2-point calibration, calibration points clearly displayed on the LCD screen;
Replaceable Electrode, Excellent Cost-Performance
Specially designed steel threaded interface electrode, length 103 mm tapering to 8 mm diameter measuring head. This electrode design allows easy insertion into test tubes and small-diameter containers for sample measurement;
Stable Reading Indicator Function
During measurement, an hourglass icon will be displayed on the screen. Once the reading stabilizes, the hourglass icon disappears and the reading can be taken:
Battery Alert and Auto Power-Off Function
CR2032 large-capacity coin cell battery, long service life. When battery power is low, a low battery indicator will appear on the display;
As needed, auto power-off can be set to 8 minutes or 60 minutes, or disabled to extend battery life;

Case Studies
Municipal Wastewater Treatment · Hanna — Stock Configuration Case
Project Overview
The site is the inlet, biological and outlet stages of a municipal plant. The customer wanted Hanna properly configured on the existing plant, with the aim of covering portable and laboratory water testing with Hanna instruments.
Technical Challenges
What actually causes trouble is high solids and corrosive fractions, with large diurnal flow swings, and effluent parameters drift and probes foul with sludge and biofilm. All of this means the Hanna configuration has to involve selected by parameter set, accuracy and field portability.
Configuration
Supply and installation were organised through the stock channel: configuring from stock and delivered quickly. On site this meant selected by parameter set, accuracy and field portability, checked line by line against: stable compliance with Grade 1A discharge limits and online data reporting.
Performance
After commissioning the outcome is results available on site, reducing lab re-checks, and the readings are now used for process tuning.
Food & Beverage · Hanna — Stock Configuration Case
Site Conditions
This is a Food & Beverage customer whose plant is at dosing, pasteurising, filling and CIP stages. The main task was covering portable and laboratory water testing with Hanna instruments.
The Problem
The difficulty lies in syrups, dairy and beverages that scale easily, under strict hygienic requirements; at the same time frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles. Specification therefore means selected by parameter set, accuracy and field portability.
What We Did
We took a stock channel approach — configuring from stock and delivered quickly. Delivery was built around selected by parameter set, accuracy and field portability, with point-by-point checks on: food-safety and hygienic design per 3-A / EHEDG.
Operating Outcome
In service the system performs as intended — results available on site, reducing lab re-checks, with routine maintenance falling noticeably.
Chemical & Pharmaceutical · Hanna — Stock Configuration Case
Application Context
reactors, metering vessels and finished-product tanks is a typical Chemical & Pharmaceutical duty. The project started from Hanna, focusing on covering portable and laboratory water testing with Hanna instruments.
Process Constraints
corrosion plus Ex protection shortens instrument life and makes downtime costly, and highly corrosive media with solvents and crystallisation, partly in explosive atmospheres only amplify it. The Hanna specification must therefore cover selected by parameter set, accuracy and field portability.
Delivery Approach
Delivery was handled as the stock channel — configuring from stock and delivered quickly. Execution centred on selected by parameter set, accuracy and field portability, together with Ex certification and GMP traceability of records.
Field Results
Operation shows the benefit clearly — results available on site, reducing lab re-checks, with confidence in this measuring point improving markedly.
Power & Energy · Hanna — Stock Configuration Case
Customer Profile
The typical setting in Power & Energy is boiler feedwater, turbine condensate and FGD/DeNOx systems. The measuring point is Hanna; the focus is covering portable and laboratory water testing with Hanna instruments.
Key Difficulties
Conditions are high temperature and pressure with both steam and saline water and, on top of that, drift under high temperature and pressure, with very costly unplanned outages, which a standard configuration cannot handle for long. The design therefore starts with selected by parameter set, accuracy and field portability.
Implementation
The scope ran through the stock channel: configuring from stock and delivered quickly. Technically it hinges on selected by parameter set, accuracy and field portability, and on these requirements: compliance with power-industry codes and unit availability targets.
Customer Benefit
In practice this means results available on site, reducing lab re-checks, which cut the workload on the site maintenance team.
