This manual introduces how to use the Extech RF20 Handheld Salinity Refractometer
EXTECH RF10/RF15 Manual
Congratulations on your purchase of the Extech RF10 or RF15 Brix Refractometer. These precision optical instruments should be handled gently and the optical surface should be avoided from touching. Careful use of these instruments will provide years of reliable service. The refractive index of a sample is measured and displayed in % Brix. The instrument has a range of 0 to 32% Brix with a resolution of 0.2%. The dimensions and weight vary for each model. The instrument requires zero adjustment and cleaning of the prism before use. To take a sample reading, a few drops of the sample liquid are placed on the measurement prism and the liquid is spread across the entire surface without air bubbles or dry spots. The sample remains on the prism for approximately 30 seconds and the sucrose concentration is determined by the intersection of the light/dark boundary observed through the eyepiece.
EXTECH RF18 Manual
The Extech RF18 Brix Refractometer is a precision optical instrument that measures the refractive index of a sample, displayed as % Brix. It requires zero adjustment before use and the prism should be cleaned with a soft cloth. The sucrose concentration is determined by observing the boundary of the light and dark fields on the scale.

The refractometers are easy to operate and provide accurate and repeatable measurements. Automatic temperature compensation models are available.
EXTECH 601100 601500 60120B Manual(1)
601XXX V1.3 11/01 pH electrode instruction sheet introduces the specifications of the 601100, 601500 and 60120B models, including dimensions, construction material, measuring range, temp. range, reference junction, reference type, isopotential point, precision, connector, cable length and storage container
EXTECH 601100 601500 60120B Manual
Extech Instruments Corporation released the pH/ORP electrodes specification sheet in 2007. The product includes 60120B and 601500 two types of pH/Ref electrodes and 601100 one type of Flat surface electrode, as well as 67500B one type of Redox ORP/Ref electrode. All electrodes use Ag/AgCl electrode filling method, fast response time, response rate is 95%/5s. The 60120B and 601500 two types of electrodes use a rugged polycarbonate structure and are equipped with a glass pH sensor. The pH range is 0 to 14 pH, and the operating temperature is 0 to 80 °C. The 601100 electrode uses a PVC structure and is suitable for pH values of solid products with minimal moisture, such as cheese, soil or electrophoretic/agar gels. The 67500B electrode uses a platinum sensing surface, a polycarbonate body and a sealed reference, which can be used for Redox ORP measurements.
EXTECH DO700 Manual
The DO700 is a digital dissolved oxygen, conductivity, TDS and pH meter. It can measure dissolved oxygen, conductivity, pH, mV and temperature parameters. Conductivity measurements also yield TDS (total dissolved solids), Salinity, and Resistivity readings. The built-in microprocessor provides automatic calibration, automatic temperature compensation, data storage, and self-diagnostics. The digital filter improves measurement speed and accuracy. The meter offers a backlit LCD display and is dust-proof and waterproof, meeting IP57. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
