Sper Scientific is a U.S.-based manufacturer with decades of experience developing environmental measurement instruments for laboratory, industrial, and field applications. The company is trusted by industry professionals for accurate, user-calibratable tools that support quality control, regulatory compliance, and safer work environments.
Sper Scientific’s product range includes pH meters and pH pens, water quality meters, dissolved oxygen probes, conductivity meters, oxygen reduction potential testers, and chlorine standards for liquid sample analysis. These water quality measurement devices are widely used in environmental quality monitoring, food and beverage analysis, agricultural testing, and scientific research requiring consistent data.
For air and environmental testing, Sper Scientific offers digital thermometers, thermocouple thermometers, infrared thermometers, carbon monoxide meters, anemometers for wind speed measurement, pressure meters, and indoor air quality instruments. Optical and specialty tools such as light meters, UV light meters, digital refractometers, EMF meters, RF meters, and acoustical calibrators support monitoring of environmental conditions, noise levels, UV exposure, and refractive index.
Many instruments feature compact, battery-powered operation and digital technology supporting laboratory operations, field technicians, HVAC professionals, and environmental testing workflows. MSE Supplies provides access to a curated selection of Sper Scientific instruments, supported by technical knowledge and reliable sourcing to help teams maintain accurate environmental testing and long-term measurement performance.
What to know before you buy
Sper Scientific makes handheld and benchtop meters for measuring water, air, sound, light and temperature in labs, plants and the field. This collection lists their meters along with buffers, probes and calibration items.
For water quality, there is a Sper Scientific benchtop pH-mV meter, a benchtop conductivity meter, a pocket conductivity and TDS meter, an optical dissolved oxygen meter, a portable chlorine meter and a portable turbidity meter kit. Support items include a pH buffer set, a pH probe with ATC, a flat surface pH electrode, turbidity sample cells and 100 NTU calibration solution. A salinity refractometer reads 0 to 28 percent.
For temperature and environment, choose from a 4-channel datalogging thermometer, SAMA range glass thermometers, humidity and temperature monitors, a dial hygrometer and the multi-function indoor air quality monitor for CO2, particulates, HCHO and TVOC. A Type 1 sound meter, an acoustical calibrator, a PAR meter, a moisture meter and a 5-channel timer round out the range. See managing laboratory conditions with Sper Scientific.
Frequently Asked Questions
Which Sper Scientific thermometer should I choose?
For logging several points at once, the 4-channel datalogging thermometer records readings over time. For simple bench checks, SAMA range total immersion glass thermometers come in -20 to 100 C and -20 to 150 C boxes of 10. Humidity monitors also read temperature for room checks.
What do I need to keep a pH meter accurate?
Calibrate with at least two buffers that bracket your samples, using the pH 4, 7 and 10 buffer set. Keep the probe wet in storage solution and rinse between samples. Replace the probe when response slows, with the pH probe with ATC or the flat surface electrode for semi-solids.
How do I check turbidity readings?
Calibrate the turbidity meter with a standard, such as the 100 NTU calibration solution, and use clean, scratch-free sample cells. Wipe cells before each reading and avoid bubbles. Spare turbidity sample cells are listed separately.
Which meter suits indoor air quality monitoring?
The multi-function indoor air quality monitor tracks CO2, PM1.0, PM2.5, PM10, HCHO and TVOC in one unit, with optional WiFi. For temperature and humidity only, the compact temperature and humidity monitor is a simpler choice for storage rooms and labs.
Can I order several Sper Scientific meters at once?
Yes. Send models and quantities through the bulk order request form, for example when equipping several rooms or field teams. For Sper Scientific items not listed here, use the quote request form.
