AquaLab Water Activity Meter: Series 3TE
The Series 3TE combines the world-class speed and accuracy of the Series 3 with internal temperature control. Using pushbuttons, you can choose a measuring temperature between 15 and 50°C. The temperature is expertly managed with internal thermoelectric (Peltier) components. No additional equipment is required. The Series 3TE has a 3 year parts/labor warranty (the best in the industry).
Reasons for using the Series 3TE:

Study effects of temperature on sample aw.

Government or company regulations on temperature-specific aw measurement.

Accelerated shelf-life studies.

Isotherm studies.

Large fluctuations in ambient temperature.

Water Activity Meter: AquaLab Series 3

Water Activity Meter: AquaLab Series 3
The AquaLab Series 3 is Decagon’s standard lab-grade water activity meter. The chilled-mirror dewpoint sensor offers unparalleled accuracy (±0.003aw) and extremely rapid read-time (<5min, including equilibration time).
Leading food and pharmaceutical companies around the world rely on the AquaLab Series 3 and Series 3TE, as do small food companies, university labs, government facilities, pet food manufacturers, and many others. The Series 3 comes with a 3-year parts/labor warranty (the best in the industry).
Reasons for using the Series 3:
•Measurement of samples that have little change in aw with temp.
•Measurement in a relatively temperature stable environment
•Superior speed and accuracy.

Water Activity Meter: AquaLab LITE

Water Activity Meter: AquaLab LITE
The AquaLab LITE is an intermediate bench-top unit that incorporates technology from both the AquaLab Series 3 (the world's fastest and most accurate water activity meter) and the portable, ultra-compact Pawkit.
The LITE is ideal for lab-based applications where ±0.015aw accuracy is adequate.
Reasons for using the AquaLab LITE:
• Easy menu-based 3-button interface.
• Fixed 5-minute read time.
• Very low maintenance: one-step cleaning procedure.
• Higher accuracy than most standard dielectric aw meters.

Water Activity Meter: Pawkit

Water Activity Meter: Pawkit
Sturdy, and Affordable.
Originally designed for government inspectors, the 4-inch Pawkit is a reliable water activity instrument for use on-the-go. To make a measurement, flip back the sensor cover and fit the Pawkit over a standard AquaLab sample cup. A push of a button brings an accurate reading within five minutes.
Pawkit owners include government inspectors, jerky manufacturers, small food companies, and production-line QA managers, among others. The Pawkit is accurate to ±0.02 aw, so it can only be used where a higher accuracy is not critical.
Reasons for using the Pawkit:
• Most affordable water activity instrument on the market.
• Spot checks and inspections away from the lab.
• Ease of use.
• Portability.

Isotherm Generator

Isotherm Generator

A moisture sorption isotherm maps the complex, product-specific relationship between water content and water activity. Considered the "fingerprint" of a food product, this curve (usually S-shaped) shows how water activity changes as water content is increased or decreased. An isotherm is the key to understanding and controlling product formulation, product stability, moisture sensitivity, temperature effects, and drying characteristics.
Until now, you could expect to pay around $100,000 for an isotherm generator (or take 2-5 weeks to create a single isotherm by hand). Using the Dynamic Dewpoint Isotherm method (DDI), AquaSorp produces highly accurate adsorption and desorption isotherm curves in 24 hours or less — at a cost that researchers and formulators can afford.

EC5 Soil Moisture Sensor

EC5 Soil Moisture Sensor

The EC-5 Soil Moisture Sensor meets the needs of those who are looking for an all-around ideal soil moisture sensors. The EC-5 obtains volumetric water content by measuring the dielectric constant of the media through the utilization of capacitance/frequency domain technology. In addition, the EC-5 sensors incorporate a high frequency oscillation, which allows the sensor to accurately measure soil moisture in any soil or soilless media with minimal salinity and textural effects.

The EC-5 continues to be our lowest-cost soil moisture sensor enabling those researchers on a tight budget to monitor soil moisture in multiple locations and depths. In the field, the robust design of the EC-5 allows the sensor to be pushed directly into undisturbed soil. However, the compact design of the EC-5 makes it possible to measure volumetric water content in labs and greenhouses. Factory calibrations are included for mineral soils, potting soils, rockwool, and perlite.

EC-5 Soil Moisture Sensor Applications:

Watershed characterization
Vadose zone monitoring
Plant-soil-water interaction studies
