HI12883 is a 3-in-1 pre-amplified multiparameter probe that measures pH, EC/TDS, and temperature in a single polypropylene body. The pH portion of the probe is constructed of a cloth junction, maintenance-free polymer gel electrolyte, and a low-temperature glass sensing bulb. The EC/TDS portion of the probe utilizes two graphite sensors to electrochemically determine conductivity and total dissolved solids. A built-in temperature sensor ensures that both pH and EC/TDS readings are compensated for temperature changes in standards and samples.
Pre-Amplified pH Electrode
The pH electrode circuit has a built-in amplifier to reduce the effects of electrical noise on high-impedance pH measurements. Electrical noise can come from motors and pumps commonly found in greenhouses. The pH electrode's single reference junction design features a cloth junction that allows ions to move between the internal gel electrolyte and the sample being measured. The advantage of the cloth junction is that it can be extracted from the probe to expose a fresh surface when readings become drifting or unstable. These features make this probe ideal for use in fertilizer solutions.
Electrochemical/C/TDS Sensor
EC/TDS readings are performed by a two-pin amperometric sensor. An alternating voltage is applied to the sensor, and the amount of current that passes between the two stainless steel pins determines the amount of dissolved ionic solids present.
Built-in Temperature Sensor
pH and EC/TDS readings must be temperature compensated to obtain accurate results. The built-in temperature sensor of the HI1288 provides fast temperature readings, which are then used to adjust the pH and EC/TDS results accordingly.
Polypropylene Body
The polypropylene body of the HI12883 features a rugged, one-piece design that houses all three sensors. This body material is suitable for a wide range of applications and, due to its durability, excels in measurements with portable meters. Fins around the spherical glass pH bulb minimize breakage from accidental impact or dropping of the electrode. Polypropylene plastic is a high-quality plastic with chemical resistance to many corrosive chemicals.
Quick-Connect DIN Connector
The HI12883 uses a quick-connect DIN connector. This type of connector is usually proprietary to the meter with which it is supplied and may not be interchangeable. The HI1288 is suitable for Hanna's HI991300 and HI991301 portable multiparameter meters.

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.
