5.0 out of 5 stars 2. A digital refractometer uses the total reflection method to measure the refractive index or related values of a liquid sample. The new Palm Abbe is a fourth-generation digital handheld refractometer that puts laboratory precision in the palm of your hand. The freezing point of the sample can also be measured and displayed in Celsius(PAL-91S) or Fahrenheit (PAL-92S). The instrument converts the refractive index of a sample to percent volume or freezing point. Refractometers measure the glycol concentration and gives the antifreeze freezing point. ATAGO Digital Pocket Ethylene Glycol Refractometer PAL-91S, easily measure the coolant in brine and other agents of Ethylene Glycol. To make an Ethylene Glycol Solution, follow the procedure below: The HI96831 takes measurements based on a sample’s refractive index. Refractive index is a measurement of how light behaves as it passes through the sample. Details about Digital Refractometer, Propylene Glycol. Old traditional analog refractometers force you to bring dangerous battery acid up to your face and eyes to take a reading. Experience the Extech Advantage. The DR series Digital Hand Refractometers are easy-to-use battery-powered instruments, … Portable Digital Refractometer, water resistant, ATC, wide measurement range. Here's how to test your system's glycol concentration with a refractometer. Measure Concentration of Propylene glycol, Accuracy ±0.4% , Range 0.0 to 90.0% (V/V) Easily measure the concerntration and freezing pointy of coolant in brine and other agents of Ethylene Glycol. Refractometer Shop is committed to providing certified, quality products from a brand you can trust. The HI96831 contains a built-in temperature sensor and is programmed with temperature compensation algorithms in accordance with the ICUMSA Methods Book for a percent by weight sucrose solution. The HI 96832 Propylene Glycol Digital Refractometer is a rugged, portable, water resistant device that utilizes the measurement of refractive index to determine the percent volume and freezing point of propylene glycol based solutions. Digital Refractometer for Ethylene Glycol Analysis - HI96831. In order for us to continue to do that effectively we are having to increase a few prices across our range of handheld refractometers. The HI96832 Digital Refractometer utilizes the measurement of refractive index to determine the percent volume and freezing points of propylene glycol based solutions. Digital Refractometer, Propylene Glycol. “Environmentally friendly” Propylene Glycol, which cannot be measured on a hydrometer, can easily be measured on a refractometer. The HI96831 is an easy-to-use tool for measuring freezing point and percent volume in ethylene glycol solutions, in the field or in the lab. It is equipped with one scale for honey moisture measuring in the range from 13 to 30 % (0.1 %). This measurement is done digitally, reducing operator influence considerably. The following graph shows the relationship between refractive index and % volume concentration for Propylene Glycol. By measuring this activity with a linear image sensor, the sample’s refractive index can be assessed and used to determine its physical properties such as concentration and density. Mo — Fr / 9.00 — 17.00| +386 5 902 99 03|WhatsApp. Hanna Service d.o.o. Condition: New – Open box. Maintaining the appropriate percent of glycol is important in glycol chillers as too low of a percentage could lead to the system freezing and rupturing while too much glycol will reduce the systems efficiency. The freezing point of the sample can also be measured and displayed. Mix solution well before use. The HI96832 has a high accuracy of ±0.2% volume and ±0.5 °C freezing point and features simple operation that … This instrument requires only a few drops of fluid for glycol testing and requires no adjustment for fluid temperature. Propylene glycol is used in glycol chillers and dispensing systems intended for food applications, such as beer and wine. A heating or cooling system with diluted glycol will have undesired performance. Misco Digital.
