HI190M-2 is a compact and lightweight magnetic stirrer. This mini-stirrer is built to last having a ABS plastic housing and cover that are resistant to many harmful chemicals. The stirring speed is adjustable from 100 to 1000 RPM. The HI190M stirrer requires very little room which is valuable when laboratory benchtop space is at a premium. Speedsafe™ mechanism Power indicating light Adjustable speed control Details Ideally, when performing electrochemistry measurements, the sample being tested should be stirred. The use of a magnetic stirrer allows for proper mixing and the sample to be homogenous in consistency and temperature. The stirring of the sample also helps speed up the response time for a sensor to achieve a stable reading Specifications Maximum Stirring Capacity 1 liter (0.26 gallons) Min. Speed Range 100 rpm Max. Speed Range 1000 rpm Installation Category II Cover Material ABS plastic Environment 0 to 50°C (32 to 122°F), RH max 95% non-condensing Power Supply 230VAC, 50/60 Hz (included) Dimensions 120 x 120 x 45 mm (4.8 x 4.8 x 1.8”) Weight 640 g (1.4 lbs.)

The HI96801 is a rugged, portable digital refractometer for food products designed to report the sugar content of aqueous solutions as % Brix. The HI96801 report the results with an accuracy of ±0.2% Brix. The operation of the meter is simplified with only two buttons: one button is to calibrate with distilled or deionized water and the other to take a measurement. All readings are automatically compensated for temperature variations according to the ICUMSA Methods Book standard and displayed within a 1.5 second response time. The sealed flint glass prism and stainless steel well are easy to clean. Just wipe with a soft cloth in preparation for the next sample.   Sample size as small as 2 metric drops (100 μl) Sealed stainless steel well with high-grade optical prism made of flint glass Fast 1.5 second response time for temperature compensated readings Details The HI96801 portable refractometer converts the refractive index of a food sample to % brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar Analysis) that documents the changes in refractive index with temperature for a percent by weight sucrose solution. The HI96801 is ideal for the analysis of fruits, energy drinks, puddings, soy milk, juices, jam, marmalade, honey, soups, jelly, tofu and condiments. The HI96801 is an easy to use tool for measuring sugar in food samples in the field or in the lab.   Designed for food sugar analysis Temperature Compensation algorithms based on sucrose solution 0 to 85% brix range with an accuracy of ± 0.2% Specification: Sugar Content Range 0 to 85% Brix Sugar Content Resolution 0.1% Brix Sugar Content Accuracy (@25ºC/77ºF) ±0.2% Brix Temperature Range 0 to 80°C (32 to 176°F) Temperature Resolution 0.1°C (0.1°F) Temperature Accuracy ±0.3 °C (±0.5 °F) Temperature Compensation automatic between 10 and 40°C (50 to 104°F) Measurement Time approximately 1.5 seconds Minimum Sample Volume 100 μL (to cover prism totally) Light Source yellow LED Sample Cell stainless steel ring and flint glass prism Auto-off after three minutes of inactivity Enclosure Rating IP65 Battery Type / Life 9V / approximately 5000 readings Dimensions / Weight 192 x 102 x 67 mm (7.6 x 4.01 x 2.6”) / 420 g (14.8 oz.)
