SXL-2 Optical Liquid Sensor, DRY-ON by Agrowtek

Electronic optical liquid sensors are durable, have no moving parts and are easy to maintain. SXL sensors can detect fluid levels in tanks, flow in pipes, or leaks in drip pans when liquid touches the sensor tip. Wide voltage range and high current capacity makes the SXL sensor practical for TTL logic, industrial PLC or direct relay control applications. 1/4" NPT threading and removable wiring terminal block with pin-out cast into the hex head makes installation or replacement fast and simple. When the output is energized a red LED illuminates the sensor body giving a visual status indication. Available in 'wet-on' and 'dry-on' configurations, or PWM output for applications requiring error indication and failure monitoring. Other intelligent functions include "stable state" switching to detect splashing, one-second output debounce and error indication from infrared flooding.

Applications

• Water Tanks
• Coolant Reservoirs
• Hydraulic Fluid Reservoirs
• Warewash Equipment
• Irrigation Systems
• High & Low Level Detection
• Leak & Overflow Detection
• Flow Detection in Pipes
• Automatic Fill/Drain Level Control

WD-00651-36 Traceable® pH Standard Buffer with Calibration, Red, pH 4; 1000 mL by Oakton

Oakton pH buffers are compared against, and are traceable to, NIST Standard Reference Materials. Each bottle includes a NIST-traceable calibration report stating accuracy at 25°C to ±0.010 pH. Color-coded and colorless buffers are available in 500-mL, 1-L, or 4-L packaging sizes. Additional values and packaging sizes are available. Store at room temperature.

Certified Reference Materials (CRM) meet federal, state, and or local agencies' strictest mandates, and deliver exact calibration results for any pH meter. A2LA ISO/IEC 17025:2005 (1750.01) (Calibration Laboratory) and ISO Guide 34 (Certified Reference Material Producer) provide highest achievable levels of product production, documentation, and accuracy. Additional accreditations include ISO 31 (content) and ISO 35 (statistical analysis). ISO 9001 ensures that world-class product standards for Materials are always met.

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.

NIST-traceable reference materials include a calibration report from an ISO 17034 and ISO 17025 accredited laboratory

• Choose from clear or color-coded standards from common calibration points
• 1000 mL (32 fl.oz.) capacity

94460-87 Traceable® Sentry Triple-Display Thermometer with Calibration; Celsius, Bottle Probe by Digi-Sense

Thermometers include a weatherproof remote sensor with a 10-ft. (3.05m) long 1/16"-diameter micro cable. The micro cable is ideal for applications that require a seal, such as a refrigerator, where a larger cable would interfere with the sealing of the door. Unplugging the external probe will activate an internal sensor for monitoring ambient temperature. Thermometer features a high-impact ABS plastic case, large LCD that updates every 10 seconds, and a simple one-button reset to clear the high/low memory. Supplied with Velcro® strip for wall mounting or has a flip-out stand for tabletop use.
