Check the vacuum levels in high-vacuum pumps, valves, and chambers with this compact gauge. Use a ring and clamp (both sold separately) to connect them to another quick-clamp high-vacuum fitting, also known as KF, QF, and NW fittings. The digital display shows measurements in torr, mbar (millibar) and hPa (hectopascal).

Made of FDA-listed materials for use with food and beverage, these sights have sanitary quick-clamp connections and an electropolished 316 stainless steel body for easy disassembly and cleaning. They meet USP (United States Pharmacopeia) Class IV standard for food applications. Sights let you visually confirm flow and inspect liquid color and clarity. Backlight the back window to increase the visibility of dark liquids.

Easy to remove for cleaning and maintenance, these flowmeter/totalizers connect to sanitary quick-clamp fittings (often called tri-clamp fittings) and measure the flow rate and volume of liquid passing through your system. You'll need a gasket and clamp (not included) to connect these to your line. They count how many times their turbine turns as liquid passes through to measure flow. To avoid clogging the turbine and other damage to the sensor, use them only with clean, low-viscosity liquids. You can reset the batch total, but you can't reset the cumulative total. Mount them directly inline with your piping system. They measure flow correctly no matter the mounting orientation.

For use in hazardous locations, these flowmeter/totalizers are FM-approved. They’re also rated NEMA 4 to protect against weather and washdowns.

These flowmeter/totalizers are calibrated with either water or solvent. You can recalibrate them in the field to other liquids, pipe, and operating conditions.

Flowmeter/totalizers with a calibration certificate traceable to NIST states that the flowmeter/totalizer has passed a test for accuracy.

90° display adapter kits let you rotate the meter’s display 90°, so you can read it easier when mounted vertically.

For dairy, food, and beverage applications that require frequent cleaning, these 3-A certified thermometers have a sanitary quick-clamp connection for easy removal.

Check the temperature of liquids in hygienic applications such as food or pharmaceutical lines and tanks. Certified by 3-A to meet sanitary design standards, the parts of these probes that will touch liquid are highly polished to minimize spots where bacteria could grow. They're rated IP67 and IP69K, so they'll withstand temporary submersion as well as the high-pressure, high-temperature washdowns that are common in hygienic cleaning practices. Made of stainless steel, harsh cleaners and sanitizers won't cause them to corrode. They have a flange that will connect to sanitary quick-clamp fittings (also known as tri-clamp fittings); they're easy to connect and remove from your line.

Program these probes with the touch screen, and select one of three colors as a visual alert for events in your process such as irregular or fluctuating temperatures. The head swivels 345° and the face rotates all the way around, so you can mount the sensor at any angle and still see the display. To trigger actions in your process line, connect these probes to remote displays, programmable logic controllers (PLCs), and other control equipment with the M12 plug. These probes meet DIN EN 60751, an industry standard for accuracy. They’re also CE marked, meaning they meet European Union safety standards.
