98766-80 Traceable Vibrating Digital Timer with Calibration by Digi-Sense

Timer vibrates when time is up to quietly nudge you during a meeting or conference. Vibrating alarm is also ideal for loud environments, where hearing a buzzer is difficult. Once the timer reaches zero in the count down mode alarm beeps for a minute and timer counts up and flashes to show elapsed time since alarm.

Traceable® Products have an individually-numbered Traceable® Certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Three alarm modes - audible, visual, and vibrating
• Increased visibility with LED light

Includes

Stand, magnetic back, one AAA battery, and NIST-traceable calibration certificate with data.

C-2710 Chlorine Dioxide Comparator (flat) by AquaPhoenix

C-2710 High Range Chlorine Dioxide Comparator is a component of K-2705 Chlorine Dioxide CHEMets Visual Test Kit and is designed to be compared against the color formed in R-7404 Chlorine Dioxide CHEMets Refill. The comparator's range is applicable for many disinfection and drinking water applications. Color standards are pink in color and cover a range of 0-10.0 ppm chlorine dixoide (ClO2).

90308-75 Irreversible 4-Point Horizontal Temperature Label, 379-410F/193-210C; 10/Pk by Digi-Sense

Labels are made up of a series of temperature-sensitive elements sealed between heat-resistant substrates with transparent windows. Each element changes color distinctly as its rated temperature is met or exceeded. The changes to the label are irreversible, providing a temperature history of the surface being monitored. The labels will not delaminate when removed, allowing them to be attached to an inspection report to serve as a permanent record. Ideal for use in the food, automotive, molding and metal working industries. Accuracy is ±1.8°F below 212°F and ±1°F above 212°F. Shelf life: 1 year after date of purchase.

• Used as a quick inspection tool that the product is in usable condition during the shipping and receiving process
• Save time and money due to costly recalls
• Self-adhesive design

TDSK180 Conductivity Solution, 85.2ppm/180uS, 1Qt by Sensorex

TDS/Conductivity instruments and sensors must be calibrated together. For a single-point calibration, select the one solution that approximates the expected conductivity or ppm level of total salts. Mixed Salt standards are the most frequently used in the field to sample naturally occurring water sources, boiler feed water, or cooling tower water. Typical river water, well water, or lake water sample will contain a mixture of several different salts. Sensorex Mixed Salt standards simulate a "Natural" mixture of common salt compounds found in these sources. Sodium sulfate, sodium bicarbonate, and sodium chloride salts are blended to provide a representative value. There are certain applications where Single Salt Solutions are preferred. NaCl Solution is routinely used to calibrate instruments measuring Sea Water or brackish water samples. Reagent grade salt and high resistivity DI water is compounded for accurate results. KCI Single Salt Solution may be used with conductivity meters that read directly in Siemens or Ohms. KCI (potassium chloride) is established as an international calibration standard for conductivity measurement. Choose the conductivity calibration solution that is right for your application.

5161 Test Strips: Chlorine, 1-750 ppm, 100 strips by AquaPhoenix

Serim® MONITOR™ for Chlorine 100-750 ppm test strips measure free chlorine. The test gives a semi-quantitative indication that chlorine-based sanitizers have the appropriate concentration of free chlorine required for use in sanitizing hard surface areas and equipment in numerous environments including food processing or preparation facilities, medical/nursing institutions, childcare or adult daycare facilities, schools and agricultural industries. A semi-quantitative estimation of the sanitizer's free chlorine concentration between 100 and 750 ppm can be made by comparing the color of the reacted indicator pad to the color chart on the bottle label. Color blocks free represent chlorine concentrations of 100, 200, 350, 500 and 750 ppm.

90433-43 Thermowell Brass, 12" Length, 1/2" Connection by Digi-Sense

To match your probe to a thermowell, first measure the distance from the probe's tip to the top of the thread (typical thread length is 0.5" for 1/2" NPT fittings). Next, match this length to the probe depth of the thermowell ("A" dimension). Other thermowell sizes and materials are available - call our Application Specialists for more information.

• Limited-Space Thermowell when you need a shorter insertion depth.
• Standard Thermowell for general-purpose applications.
• Heavy-Duty Thermowell for higher fluid velocity ratings.

PBX-106 6-Port Chemical Injection Manifold by Agrowtek

PBX-104 is a simple multi-port manifold for connecting Agrow-Dose peristaltic dosing pumps into a recirculating sample loop for injecting chemicals such as nutrients or pH buffers.

The PBX-100 series injection manifolds are often combined with a PBX-210, PBX-310, or PBX-410 sensor probe manifold for sampling of the solution prior to the injection point.
