The Palmer Wahl 524 differential pressure chart recorder produces a paper record for reviewing filter pressure drop and suitable flow or liquid-level measurement systems. Optional pens allow static pressure and temperature to be recorded alongside differential pressure.
Chart size: 12-inch circular chart with pipestand mounting.
DP ranges: Select from 0–20, 0–50, 0–100, 0–200, 0–300 or 0–400 inches of water.
Recording channels: One differential-pressure pen, with optional static-pressure and temperature pens.
Chart drive: PC-11 battery-operated multi-speed drive as standard.
Construction: Mechanical dual-bellows measurement system in a powder-coated aluminium case.
Palmer Wahl pressure and temperature chart recorders provide a paper record of measurements over time. Choose an 8-inch or 12-inch recorder with an aluminium or Pelican® case, configured for pressure, temperature or combined recording.
Recording options: Up to three pens, depending on configuration.
Chart drives: Battery-operated, with spring-wound and electric options available.
Installation: Portable and fixed-mount configurations.
The Wahl DP Series differential pressure transmitter measures the pressure difference between two points in a compatible gas or liquid system. Its dual pressure ports support filter pressure-drop monitoring and industrial process measurement.

Accuracy: Ultra-high, Standard and Economy options to suit the measurement requirement.
Connections: Selectable process threads and electrical connectors for installation or replacement work.
The Wahl SS and CS Series pressure transmitters convert process pressure into an electrical signal for compatible PLCs, controllers, indicators and data acquisition systems. Choose a silicon or ceramic sensor to suit the pressure range and measured medium.
SS Series: Silicon pressure sensor with a stainless steel diaphragm.
CS Series: Dry ceramic pressure sensor for applications requiring suitable chemical and corrosion resistance.
Signal options: 4–20 mA or voltage output, selected when ordering.
Accuracy options: 0.05%, 0.08% or 0.10% of full scale, subject to the specified operating conditions.
Installation: Compact 304 stainless steel housing with selectable process and electrical connections.
The Sekonic C-7000 handheld spectrometer measures light spectrum, illuminance, colour temperature and colour rendering for professional lighting evaluation. Compare LED and other light sources using one portable instrument.
Spectral measurement: 380 to 780 nm.
Lighting analysis: CRI, chromaticity and PPFD, with expanded colour metrics available on supported firmware.
Data handling: Store measurements and export spectral data through C-7000 Utility software.
Dickson OCEAView™ brings wireless environmental monitoring, alarm notifications and traceable records into one platform. Monitor temperature, humidity and other critical parameters using compatible data loggers and sensors for refrigerators, freezers, laboratories, pharmaceutical storage and cold rooms.
Connected monitoring: LoRaWAN and Bluetooth logger options for fixed equipment and mobile applications.
Actionable alerts: Email, SMS and voice notification options for excursions and technical alarms.
Traceable records: Audit trails, measurement history and reporting tools.
The Evikon E2218-DM duct humidity and temperature transmitter measures air conditions inside ventilation ducts and provides calculated dew point and absolute humidity values.
Duct installation: 200 mm insertion probe.
Analog signals: Two configurable outputs, selectable as 4–20 mA or 0–10 V.
The Evikon E2418-DF differential pressure transmitter measures small pressure differences in dry, clean air. Connect it to a compatible building management system, PLC or monitoring system for HVAC and room pressure applications.
Models: E2418-DF-50 and E2418-DF-500.
Measuring ranges: −50 to +50 Pa or −500 to +500 Pa.
Analogue outputs: Two outputs selectable as 4–20 mA or 0–10 V.
The Evikon E2244 humidity and temperature transmitter measures relative humidity and air temperature for connection to controllers, monitoring instruments and building management systems.
Measurements: Relative humidity and temperature in air and non-aggressive gases.
Analog outputs: 2 × 4–20 mA and 2 × 0–10 V.
Construction: IP65-rated enclosure.
Mounting: E2244 wall-mount and E2244-DM duct-mount versions.
The Ryutai Kogyo EM series metal tube variable area flowmeter measures flow with a magnetically coupled indicator. Select local indication or additional electrical functions to suit your installation.
Fluid options: Models for clean liquids, gases and steam.
Body sizes: 15A to 150A, depending on model.
Functions: Local flow display, analogue output, totalising, pulse output and alarms, depending on configuration.
Replacement enquiries: EM-series selection is available for older MCF installations, subject to compatibility checks.
Check heat conditions at worksites, sports facilities and outdoor activity areas with the Sato SK-170GT WBGT monitor. Its built-in black globe accounts for radiant heat while the instrument displays WBGT, air temperature, globe temperature and relative humidity.
Choose indoor or outdoor measurement mode, set a WBGT alarm and review maximum or minimum readings. One 9 V battery and a hard carrying case are included.
