Product Overview
HI190M-1 is a compact and lightweight magnetic stirrer. This mini stirrer features an ABS plastic housing and cover, resistant to many harmful chemicals and built to last. Stirring speed is adjustable from 100 to 1000 rpm. The HI190M stirrer requires very little space, which is invaluable when laboratory bench space is at a premium.

Speedsafe™ mechanism
-
Power indicator light
-
Adjustable speed control
-
Ideally, samples to be measured should be stirred during electrochemical measurements. Proper mixing can be achieved using a magnetic stirrer, and the sample is uniform in consistency and temperature. Stirring the sample also helps speed up the sensor's response time to achieve stable readings.
-
Compact and cost-effective
-
The HI190M-1 mini magnetic stirrer is compact and lightweight, making it easy to operate in laboratory environments. This durable, space-saving stirrer no longer focuses on the limited area on the laboratory bench. The power indicator LED also reassures users from a distance that the stirrer is running. The durable plastic cover will resist the harmful effects of accidentally spilled chemicals. The HI190M-1 micro magnetic stirrer is cost-effective for customers who do not need the added expense of a heating element. The advanced design incorporates electronic control, allowing users to easily and precisely adjust the speed.
-
Speedsafe™
-
Typically in the laboratory, the sample is removed from the stirrer before the speed is sufficiently reduced. Usually, this causes the internal motor to accelerate until it is damaged. To control speed through viscosity changes or load removal, the HI190M-1 mini magnetic stirrer incorporates the Speedsafe™ mechanism. With Speedsafe™, a speed sensing device (photoelectric sensor) is connected to an FVC (frequency-to-voltage converter) to monitor the stirring speed. When the speed reaches a preset maximum level, the speed limiter turns off the VCO (voltage-controlled oscillator) to reduce the motor speed. This ensures that when the load is suddenly removed from the stirrer, the motor will not accelerate to a high speed that is harmful to both the user and the stirrer; this is not commonly found in conventional stirrers.

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.
