4121-1 4100-C Single Channel Controller Panel with One ZD 21 Transmitter by GfG

The 4100 one-channel and the 4-channel 4400 gas warning systems offer safe and reliable gas detection.

Alarm points

Each alarm can be adjusted separately. False alarms are eliminated with the adjustable alarm delay. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be selected to be latching / non-latching or resettable / non resettable.

Alarm relays

The controller provides four voltage-free relays for the three alarms in addition to one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.

Features

• Complete 1-to-4 channel controller / gas monitoring system
• 110 VAC or 24 VAC
• Case-mounted horn / strobe
• Security lock
• Slim-line design

Additional features

The 4100 control panel stores peak values and offers an additional 4-20 mA output. The 4400 control panel offers the ability to connect up to 4 transmitters and comes standard with an additional 24 VAC output for solenoid control.

WD-27502-05 Cole-Parmer® Ion-Selective Electrode (ISE), Bromide, Double-Junction, BNC by Oakton

Whether your application involves end point determinations in potentiometric titrations or continuous monitoring of specific ions, we can help you find the right electrode for the job. These fast and accurate electrodes do not require an external reference - they're easier to use than separate sensing and reference half-cell electrodes. All Cole-Parmer electrodes are double-junction combination ion-selective electrodes and are convenient to use in places where two electrodes won't fit. All electrodes include a 30-mL bottle of reference solution, a reference filling pipette, 1-m cable, BNC connector, and an instruction manual. Solid-state electrodes also have twelve polishing strips.

Economy Epoxy Electrodes have a durable epoxy body and are well-suited for portable field applications. Outer reference chamber is silver-free and resists contamination. These electrodes are refillable.

Laboratory Glass Electrodes are double-junction in design, with a glass body that provides high-quality measurements for your laboratory applications. Improved glass seal enhances performance and reliability. Sealed inner junctions and refillable outer junctions accommodate special reference fill solutions - ideal for low-concentration measurements. Use electrodes with a meter that has a resolution of 0.1 mV for the most accurate results. Many meters in our "pH/Ion Meters" section have 0.1 mV resolution; several also give direct readings in ppm. For monitoring ions not listed below, call our Application Specialists for more electrode application information.

• Cost-effective choices that are easy to use
• Easily fit into small spaces - no additional reference electrode is needed
• Bromide (Br^-) ISE with glass body

0563 2512 512-2 - Digital Differential Pressure Measuring Instrument with App Connection by Testo

Differential pressure measurements fast, easy and precise: This is what the testo 512-1 and testo 512-2 measuring instruments stand for. The two models differ in their measuring range: testo 512-1 measures up to 80 in H2O, and the testo 512-2 up to 800 in H2O.

In practical use, they convince with their flexibility and variety of applications. Checking the gas pressure on burners by measuring gas flow pressure and static gas pressure is just as quick and precise as checking filters and Pitot tube measurement in the ventilation duct.

The position-independent differential pressure sensor ensures reliable and highly accurate measurement results in both instruments. The testo Smart App for smartphones and tablets supports you with these functions:

• Configure measuring instrument
• Display graphical measured value curve
• Save measurement data
• Manage customers and measuring points
• Documentation on site
• E-mail dispatch of the report
• Second screen display (via Smart App)

• testo 512-1 with position-independent differential pressure sensor with high accuracy up to 80 inH20 for checking filters and for Pitot tube measurement in the ventilation duct, incl. volume flow calculation in measuring instrument and App
• testo 512-2 with a large measuring range up to 800 in H2O
• Fast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart App
• Audible alarm sounds if a limit value is exceeded
• Durability through compact design with robust housing

37804-07 Traceable® Scientific Single-Input RTD Thermometer with Calibration; Bullet Probe by Digi-Sense

This high-precision thermometer is ideal for measuring temperatures in gas systems, reagents, chemical solutions, soil, water baths, ovens, incubators, pharmaceuticals, foods and wastewater. Designed for years of reliable service even in severe environments, the meter features a splash proof membrane keypad. A high-contrast 1/2"-high LCD makes the thermometer easy to read in all types of light. The meter features memory and hold function, internal datalogger that captures the min/max temperature every hour for a 24-hours period, and °F/°C selection. For easy reading, the meter can be changed to display one, two, or three significant numbers after the decimal point. The fast-response general purpose probe (included) displays even the slightest temperature change instantly. Readings are updated three times a second. The internal memory can be downloaded into a computer using optional software 90080-21.

Traceable® products are calibrated to NIST-traceable standards and ready to use as soon as you receive it. Each product goes through an intense vetting process before it can carry the Traceable name, and it includes NIST-traceable certification. This means that a 17025-accredited calibration test lab has confirmed that the product meets or exceeds all stated specifications, saving you both time and money by not having to calibrate separately.

NIST-traceable calibration also helps you meet quality standards and regulatory compliance for ISO, FDA, cGMP, VFC, CAP, CLIA and Joint Commission requirements.

• Get accurate, reliable measurements with included NIST-traceable calibration
