Dangerous Gas Monitor/Alarm
Low Cost Solution to Monitoring Dangerous Gases and Vapors
The Model SBG200 is capable of monitoring over 100 combustible and toxic gases. It is housed in a rustproof NEMA 2 case which protects the solid state circuitry from damage and yet is small enough (6.75"H x 4.9"W x 2"D) to be mounted wherever needed. It features circuitry to prevent false alarms and provide maintenance free operation. The Color-Coded Taut Band Meter gives reliable indication of background gas and classifies exposure as Safe (green), Warning (yellow) and Danger (red). The flashing light and audible alarm functions can be set to alarm at specific setpoints. The sensor is safe in all environments and cannot be poisoned by overexposure to gases. A remote function contact is provided to connect to central panel or to turn on remote alarms, ventilation units and other emergency devices. The Model SBG200 is powered by a 115V power supply; simply plug it into a normal wall outlet and it supplies the monitor with low voltage DC current making it safe in dangerous atmospheres. Price includes factory calibration and manual. Specifications Circuitry: Solid state Relay Output: 1.5 amps; 120 volts (max) Power: 115VAC/5.5VDC Size: 6.75"H x 4.9"W x 2"H Weight: 2 lbs Note: Please specify gas/vapor to be detected and desired alarm calibration in ppm (parts per million) or % LEL (lower explosive limit).
_____________________________________________________________________________________________________ Dangerous Gas Leak Detectors
The Model 501 Gas Tracer is inexpensive and easy to use. It is designed to indicate the presence of combustible and/or toxic gases by relative magnitude and will quickly pin-point the source of contaminant gas leaks. It responds to gas concentrations well below most OSHA ceilings. With its three switch selectable sensitivity ranges, the Model 501 is capable of detecting the concentration level of some gases as low as 1 ppm. Higher concentrations will correspondingly produce higher meter readings. Other features include battery check, alarm switch for audible signaling of leaks, ABS housing with Lexan meter face and guarded sensor which gives it high impact resistance, solid state sensor designed for over 50,000 exposures and rust proof belt clip for easy no hand carriage. Price includes batteries (Model 501NK: battery and recharger) carrying case and manual.

_____________________________________________________________________________________________________ Ultrasonic Leak Detector Kit Model 3000M Ultrasonic Testing Saves You Time and Money!
Advantages:
The Model 3000M Sonic Leak Detector can save you time and money by preventing disastrous shutdowns. Discover leaks which were previously difficult to find by checking machinery while it is operating. Leaks and other vibration sources produce a broad band of ultrasonic noise. Experiments have shown that peak amplitudes for many of these problem areas are around 45KHz; well above the sounds which the human ear can hear. The 3000M will translate the ultrasonic frquences between 30 and 50 KHz into an audible output. In addition, the 90° taut-band meter provides visual indication of signal strength. As a result, the user can quickly identify the source of the problem. The 3000M is lightweight with a belt-clip and probe holder which makes it easy to wear; the controls are located on the top of the detector unit for easy access. The high resolution stereo headphones come with individual volume control for each ear; they are comfortable enough to wear all day. Two individual probes are included, a contact probe for detecting ultrasonic sound transmitted along the surface of a rigid structure, and a air probe for detecting airborned ultrasonic signals in a 22° angle from its tuned directional cone which ignores all sonic background frequencies commonly found in a noisy factory. The air probe makes it easy to pinpoint leaks even at great distances. The focusing extension and fine extension attach to the air probe to further narrow the search patterns f the air probe making it easier and faster to find the source of the leak. The ultrasonic transmitter (included) provides a convenient means for checking tightness control in non-pressurized compartments such as tanks, cars, chambers and containers. Simply place the transmitter in the container under investigation and switch it on to emit an ultrasonic signal; this signal will pass through any orifice or faulty seal and will be quickly located by the 3000M. The 3000M can also be connected to a tape recorder providing valuable reference data for later use. Price includes battery, charger, air and contact probes, focusing and fine extension adaptors, headphone, transmitting sound generator, rugged foam-lined carrying case and manual. Specifications Sensitivity: 2db signal noise ration 10’ std cc/sec leak rate Circuitry: Solid state integrated circuit Temperature Range: -10° to 150°F Meter: 100 micro amp 90° taut-baud needle movement, 0-100 linear scale and 0-40 dB range Repeatability: 99% Detector Construction: Rugged .050 aluminum Power: Detector: self contained NiCad rechargeable 9VDC ±.7V at 10 mA Transmitter: 9VDC ±.7V at 10mA Size: 7.5” x 4.5” x 1.75”; Case: 19” x 15” x 4” Weight 9.25 lbs (including case and accessories)
