The Hanna Instruments HI 4114-51 is a combination (full-cell) ion selective electrode (ISE) for measurement of potassium ions with a ceramic junction, polyvinyl chloride (PVC) membrane, O-ring seal between sensor sensing module and sensor handle, Bayonet Neill-Concelman (BNC) connector, and is refillable. Ion selective electrodes (ISE) respond selectively to ions in the presence of other ions, and are commonly used for water testing, and to analyze biological samples in hydroponics, aquaculture, and agriculture. The ceramic junction of this electrode provides long electrode life in harsh environments, such as wine. The PVC membrane is impregnated with the organic ion exchanger valinomycin. The electrode body is 120mm high and has an outside diameter of 12mm. There is an O-ring seal between sensing module and sensor handle for protection against substances and the electrode is refillable to prolong electrode life. A BNC connector provides tight cable connections.

All electrodes are probes or sensors, but not all probes are electrodes or sensors. Probes, such as temperature probes, are used to penetrate a material for measurement. Common electrode types are pH, total dissolved solid (TDS), and ion selective electrode (ISE). Electrodes can be half-cell or full-cell (also called combination) types. They can be refillable or non-refillable. Housing material is typically glass or epoxy, and sensors are commonly made with stainless steel or a glass bulb. pH electrodes, which measure the pH of a substance, often have a glass bulb. The bulb senses hydrogen ions, and generates a millivoltage that is picked up by the filling solution and transferred to a wire that connects to the pH meter. Ion selective electrodes (ISEs) respond selectively to i...

This wide range of hydrometers are used in the food and beverage, and other industries to measure % sucrose by weight in various ranges from 0 degrees to 101 degrees Brix, and include a convenient, built-in thermometer with a temperature scale of 0/50 degrees C and mercury-free blue spirit organic liquid fill. Made of lead free ballast and glass, these combined form hydrometers are 381mm (15”) long, and are individually serialized and conform to the accuracy requirements for ASTM thermo-hydrometers. Temperature standardization is 20 degrees C. DURAC Safety Combined Form Thermo-Hydrometers are hand inspected by our U.S. quality team in our exclusive triple accredited/registered ISO/IEC 17025:2005 and A2LA Accredited Calibration Laboratory; internationally recognized and accepted by the signatory economies of the ILAC /MRA and located in our ISO 14001:2004 Environmental Management System registered facility. They are packaged with a multi-language (English, French, German, Italian, Portuguese, and Spanish) Statement of Accuracy indicating accuracy traceable to NIST. Note: Combined form hydrometers should be stored in a clean, dry, safe place, and should not be subjected to extreme temperatures. Enclosed thermometers should be used as a general reference only. For temperature critical applications, a calibrated standard thermometer is recommended.

Dwyer RMB-55 Rate-Master Flowmeter S12J 30-400 SCFH Air

Manufacturer: Dwyer Instruments, Inc. Brand: Dwyer

The Rate-Master® Flowmeter line of direct reading precision flowmeters incorporates many unique user features at moderate cost. These low cost flowmeters are ideal for general use. The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background. All Rate-Master® flowmeter bodies are injection molded of tough, clear, shatter-proof polycarbonate plastic around a precision tapered pin. The result is accurate and repeatable readings. The single piece plastic body is mounted to a stainless steel back bone into which pipe thread inserts are welded to absorb piping torque. The Rate-Master® flowmeter can be neatly through-panel mounted to keep flow tube centers in the same plane as the panel surface or surface mounted on the panel by means of tapped holes in the backbone. When through-panel mounted, the bezel automatically positions the instrument at the correct depth in the panel cutout. Surface mounted units can also be held in place by the piping. All mounting hardware plus installation and operating instructions are included. (Picture shows standard range).
