Product Features

Riken Keiki SP-220-SC Gas Leak Detector

The lightweight SP-220-SC is a highly sensitive Gas Leak Detector for Toxic, Combustible and CFC Freon gases.

The SP-220 Type SC version uses a hot-wire semiconductor sensor (MOS) that can detect a range of target gases.

Select from any of the forty listed gases for a direct reading referenced from a single calibration gas (PH3).

This new model SP-220-SC replaces the SP-205ASC used by the semiconductor industry for high sensitivity leak checking of hydride gases.

Riken Keiki SP-220-M / L / ML Gas Leak Detector

The SP-220 Type M / L and ML are highly sensitive Gas Leak Detectors for Natural Gas as well as LPG

Riken Keiki SP-220- F Gas Leak Detector

The SP-220 Type F is a version exclusively for CFC Gases.

Riken Keiki SP-220-H Gas Leak Detector

The SP-220 Type H2 is a version for Hydrogen

Riken Keiki SP-220-FUM

The SP-220 Type FUM is a version for Fumigation gases and can detect 7 Fumigation Gases including Phosphine as well as Sulfuryl Fluoride.

General Features

The SP-220 Series has an integral pump, LCD display with backlight, moulded rubber cover as well as an LED light and weather protection.
The Instruments have an IP-55 rating for dust and water ingress as well as Snap logging (128 readings) and data-logging (256 data points). These features allow for accurate record keeping in addition to testing accountability.

The SP-220 also has the ability to zero out background gas to help identify if you are getting closer to a leak source.
