90550-46 Dampened Adjustable Angle Bimetal Thermometer, 3" Dial, 24" L/50-550F/10-290C by Digi-Sense

Accuracy is ±1% full-scale when stem is immersed 2" in liquids or 4" in gases (immerse models with a 2.5" stem length 2" in gases). Measured stem length from the top of the threads to the bottom tip of the stem. Stem dia is 0.25"; threaded connection is 1/2" NPT(M). All thermometers meet or exceed ASME B40.3 standards. Maximum environmental temperature for glass lens thermometers is 500°F (148°C).

• Dampened movement
• More economical than silicone gauges
• Greater temperature range than silicone-filled gauges
• Anti-parallax dial for accurate readings
• Eliminate the risk of a leaking case and cross-contamination
• Hermetically sealed per ASME B40.3 standard to prevent fogging and protect against tough environments
• Rugged 304 stainless steel construction with a clear glass lens
• Recalibrate using the external reset screw

0554 2222 Cable Handle for Connecting Testo 440 Probe Heads by Testo

You can easily expand your portfolio of probes by connecting the handle to different probe heads. The extendable telescope for air velocity probes can also easily be connected to the handle.

The readings are transmitted to your measuring instrument (please order separately) via the fixed cable (cable length 1.4 m). Particularly useful: operate the measuring instrument by pressing the button on the handle - for example, to store individual readings.

Please note that you need our adapter (order number 0554 2160) to connect probe heads for air velocity measurement or the extendable telescope for air velocity measurement to the handle.

• Transmit readings via cable
• The handle can easily be connected to a probe head or extendable telescope
• Use the button on the handle to store individual readings in the compatible measuring instrument

Includes:

Cable handle with fixed cable (cable length 1.4 m).

A-0174 Electrode for I-1000 pH meter by AquaPhoenix

A-0174 is one replacement electrode and cap for the I-1000 pH Meter. When your pH Meter fails to calibrate or is showing fluctuating readings in calibration standards, replacing your electrode may be required.

The electrode and pH Meter are both manufactured by Oakton Instruments, Inc.
