3540 Bench pH/conductivity Meter (US)

• Simultaneous display of pH and conductivity
  
• 2 independent channels to prevent interference between probes
  
• Additional modes for resistivity, salinity, TDS and mV
  
• Data logger with auto save/print options
  
• Storage of up to 500 readings (250 for each mode)
  
  The 3540 is ideal for use in all laboratories where pH and conductivity analyses are required. The setup menu gives quick and easy access to the whole range of instrument, pH and conductivity measurement options. Calibration of both channels is automatic, with the option to select 1, 2 or 3 calibration points. The pH channel can also display mV values if required.

  The 3540 conductivity pH meter is supplied with a glass combination pH electrode (924 005), glass conductivity probe (K=1 027 013), electrode stand and holder, ATC probe (027 500), BNC shorting plug, pH buffers and US power supply.

Traceable Calibrated Fridge/Freezer Digital Thermometer

Monitor minimum and maximum temperatures— all at a single glance!

Item #: ATC1
 

• Includes NIST-Traceable certificate from A2LA accredited (1750.01) calibration laboratory
• Triple-display—shows high, low, and current temperature simultaneously
• Features a bottle probe, probe is sealed in a glycol solution
• Min/max memory
• High and low settable alarms
• 1-year warranty

Easily monitor temperature in liquids, baths, air/gas, incubators, refrigerators, or freezers. Keep track of temperature conditions overnight or for any time period—minimum and maximum temperatures are stored until the memory is cleared. Models feature a triple display that simultaneously shows current, minimum, and maximum temperatures. Set high and low alarms in 1° increments; the alarm sounds when temperature rises above or falls below set points, and continues to sound even if temperature returns to nonalarm range. The thermometer reads ambient temperature or probe temperature. The probe is attached to a 10-ft (3 m) micro-cable that permits doors to close on it; the probe and cable are both submersible. Mount the meter with included hook-and-loop strips, and wall-mount slots, or use the flip-open stand on the benchtop.

Model 94460-72 is supplied with a special bottle probe specifically designed for refrigerator/freezer applications. The temperature sensor is enclosed in a bottle, which protects it from rapid temperature changes when the refrigerator door is opened

Guaranteed to have at least one year of calibration remaining on certificate.

Traceable^® Products have an individually-numbered Traceable^® Certificate provided with each unit.
