73-0023 Gaswatch 3 Portable Gas Monitor, CO, Electrochemical sensor, with alligator clip by RKI Instruments

The GasWatch 3 is the world's smallest and lightest single-gas monitor. Weighing just 1.6 ounces, its compact form affords great comfort and flexibility in how you choose to wear it. It can be worn on your wrist as a watch, or clipped into your breathing zone on your lapel, hard hat or other safety equipment with its alligator clip.

The 5 different GasWatch 3 models can protect you from oxygen deficiency [GW-3(O2)], exposure to carbon monoxide [GW-3(CO)] or exposure to hydrogen sulfide [GW-3(H2S)]. A hydrogen compensated model [GW-3(C-)] can protect those who work in steel mills, refineries or other environments where hydrogen is present from carbon monoxide exposure. The dual sensor model [GW-3(CX)] can simultaneously protect you from oxygen deficiency and carbon monoxide exposure.

A small, field-replaceable, coin-type lithium-ion battery gives the GasWatch 3 up to 4,000 hours of continuous operation. The hydrogen compensated CO can operate up to 2,500 hours, and the dual sensor CO/O2 model will get up to 2,000 hours of continuous operation.

The great battery life coupled with a 3-year warranty* gives the GasWatch 3 tremendous value and a low cost of ownership.

Note: *2-year for galvanic sensor on the O2 model

08541-41 RTD Stranded Wire, 28-Gauge, TFE/FEP Insulation, Duplex, 100-ft Spool by Digi-Sense

Three-strand RTD wire features excellent resistance to abrasion, chemicals, and moisture. Each silver-plated copper strad is color-coded with fluorinated ethylene propylene (FEP). The three starnds are twisted to increase flexibility and minimize electromagnetic noise, then jacketed in white FEP. The FEP insulation provides temperature resistance up to 400°F, and chemical resistance to solvents, acids, and oils. Additionally, the insulation protects the wire from thermal aging, while maintaining its strength and flexibility.

• 100-foot spool of RTD wire- cut to any lenght needed!

18004-20 Traceable ONE Single-Use USB Temperature Data Logger, 60 Day, 6 Minute Interval, 12 to 14°C; 10/pk by Digi-Sense

These data loggers can be used for monitoring and recording temperatures during shipments, storage, or experiments. They are ideal for food, pharmaceutical, or laboratory use any application where a small accurate datalogger is required.

The data logger features a time delay of 30 minutes so the logger will not alert when the temperature is within the alarm zone, until the delay time elapses. Protective plastic pouch keeps logger dry, eliminating concerns when shipping materials with cold packs, ice, or in damp environments. To maintain IP67 waterproof rating, do not tear open pouch before data download.

Products have an individually-numbered 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.

• LED alarm indicator for visual status indication
• Time delay of 30 minutes before logging begins for enhanced logging accuracy
• Protective plastic pouch maintains waterproof IP67 rating
• Bar code for in-house scanning
• Includes NIST-Traceable certificate from our A2LA accredited (1750.01) calibration laboratory
• Compact, single-use datalogger with 60 day logging duration in 6 minute intervals
• Low to High alarm parameter range of 12 to 14°C

Includes

Battery (3.0 V CR2450 lithium) and NIST-Traceable calibration certificate with data.

36225-92 104APL324 Variable- Time Output Controller, 2400 Watts, 240 V 50/60 Hz by Digi-Sense

This timed control turns the output load on and off and then repeats the cycle. Each position on the knob from LO to HI represents a specific cycle time where the on time ranges from 6 to 100 percent. For example the LO setting represents a total cycle of 60 seconds with an on time of 4 seconds. This type of control can be used to regulate the temperature of resistive loads. The pilot light on the front will glow when the load is on.

Includes

Model 36225-91 has a 6-ft cord with U.S. plug; model 36225-92 has a 4-ft cord without plug.
