Specialist measurement instruments help answer questions about material moisture, liquid properties, gas concentration and outdoor conditions. Explore instruments from SL Measurement by the task you need to perform, with links to product details and sensor options below.
Moisture meters for wood, building materials and paper
Choose a moisture meter designed for the material being inspected. Material composition, density and thickness affect the measurement, so a meter intended for timber should not automatically be used to assess paper or cardboard.
Select the instrument according to the liquid property you need to measure. A pH meter measures acidity or alkalinity, while a refractometer uses refractive index and a suitable scale to assess liquid concentration.
Sato SK-650PH desktop pH meter and probe options — a bench instrument with separately purchased electrodes. The product page includes PHP-31 and 640S-series probe options for different sample arrangements.
Gas measurement requires a sensor selected for the target gas and concentration range. Specify the installation conditions, sensor position and receiving system when choosing a transmitter.
Evikon E2618 gas transmitters — gas-specific configurations with attached or remote sensors, analogue outputs and RS485 Modbus RTU. Confirm the exact gas and model required.
Wind and rainfall sensors
Weather sensors provide measurements to a compatible indicator, counter or recording system. Select the sensor and receiving equipment together, including the required signal, cable length and power supply.
Sato 7980-S-13 wind speed sensor — a three-cup anemometer with an analogue output for connection to compatible monitoring equipment.
For control applications, define the operating conditions and the variable you need to regulate. Mechanical pressure regulation and electrical signal control require different equipment.
KOFLOC 6800 gas back pressure regulator — regulates upstream gas pressure by releasing gas when pressure exceeds the selected setting. Match the model to the gas, pressure and required exhaust flow.
Yashima temperature and universal controller — accepts supported thermocouple, RTD, current and voltage inputs. Confirm the input, output and control requirements for your installation.
Countdown timers for repeated tasks
A dedicated timer provides a consistent timing reference for workstation routines and repeated processes.
Sato TM-27 and TM-29 non-contact timers — start a countdown using a hand movement over the sensor. Choose the model according to the timing range and adjustment interval required.
Help selecting an instrument or sensor
Tell us what you need to measure, the material or medium involved and the expected measurement range. For connected instruments, include the required output and the model of the receiving controller or recorder.
For replacement probes or sensors, send the existing part number and instrument model so compatibility can be checked.
Monitor outdoor wind conditions with the Sato WVAT6D0-3-00 digital wind speed and direction indicator and matching W639-ED1 sensor. The system provides a local display and configurable alarms for site monitoring.
Wind measurement: Sensor range of 2 to 90 m/s and 0 to 360°.
Display: Instantaneous and mean wind speed, with 16-point wind direction indication.
Alerts: Configurable wind alarms with contact, light and audible notification.
System selection: Specify the indicator, sensor, cable and required output options together.
The Sato 7980-S-40 tipping bucket rainfall sensor converts collected rainfall into electrical contact pulses for a compatible external recorder or counter. Its stainless steel construction and two-wire connection suit installations requiring rainfall measurement at a separate monitoring point.
Rainfall resolution: 0.5 mm per bucket tip.
Collector opening: 200 mm diameter.
Signal: Reed-switch contact output.
System connection: Two-conductor cable to compatible receiving equipment.
The KOFLOC 6800 series regulates pressure on the upstream side of a gas system by releasing gas when pressure exceeds the selected setting. Its compact design suits panel-mounted equipment and tank pressure control.
Pressure settings: 0.01–0.3 or 0.01–0.6 MPa(G), depending on model.
Maximum exhaust flow: 0.8, 1 or 10 L/min, depending on model and operating conditions.
Connections: Rc 1/4 or Rc 1/8.
Selection: Four versions with material options to suit the gas.
Check moisture in paper and cardboard without puncturing the material using the Exotek MC-60CPA pinless moisture meter. Place the sensor against the surface for quick checks on suitable paper rolls, stacks and reams.
Non-destructive measurement: Capacitance sensing without penetrating pins.
Applications: Paper production, printing, packaging and incoming material inspection.
Material selection: Select the appropriate material group for the paper or board being checked.
Portable operation: Handheld digital meter powered by a 9 V battery.
Check timber and building materials without penetrating pins using the Exotek MC-380XCA moisture meter. Two scanning modes help you compare moisture indications near the surface and through a greater material depth.
Dual scanning modes: Nominal 10 mm and up to 100 mm scanning depths, depending on the material.
Material selection: Wood and building-material groups with density settings.
Start a countdown without pressing a button with the Sato TM-27 and TM-29 non-contact timers. Hold your hand over the sensor to begin timing, making them practical for handwashing stations, food preparation areas and repetitive workstation tasks.
TM-27: Set 5–90 seconds in 5-second steps for short, repeated tasks.
TM-29: Set 1 second to 99 minutes 59 seconds in 1-second steps.
Touchless operation: Start the countdown and silence the sounding alarm using the sensor.
Battery operation: Each model uses three AAA batteries.
Monnit ALTA Soil Moisture Sensor measures soil moisture tension & soil temperature within the soil. It uses a resistive granular matrix element to accurately measure the matric water potential (soil moisture tension) in the soil and a thermistor based temperature element to measure temperature.
- Safe to use in both hot & freezing temperatures - Reports matric potential (soil water tension) - Moisture readings in centibar & kPa - 0 to 240 centibar (kPA) - Will not dissolve in soil - Internally compensated for commonly found salinity levels - Easy to install and use compared to traditional tensiometers - Stainless steel electrodes - No maintenance required - Temperature readings in C/F. - 5 ft removable lead
Monnit ALTA Wireless Carbon Dioxide Sensor uses an ultra low-power, high-performance CO2 sensor to measure the amount of carbon dioxide in ambient air.
- Measures 0 to 10000 ppm CO2 - Accurate to +/- 45 ppm + 3% of reading - Sensor produces instantaneous CO2 readings and 8 hour time weighted average(TWA) readings
Measure wind speed for a connected monitoring system with the Sato 7980-S-13 three-cup wind speed sensor. Built-in signal conversion and linearisation provide an analogue output proportional to wind speed.
