20250-63 AC/DC Clamp Meter with Bluetooth® Connectivity by Digi-Sense

Using our free Digi-Sense D/S Meter app, this AC/DC clamp meter with Bluetooth® technology allows you to transmit data directly to your Android or iOS device. Now you can view data at a safe distance from dangerous equipment or hazardous locations and even use your smart device as a real-time secondary display for checking measurements, eliminating the need to write down readings on paper. The results are automatically stored in the app with a date-and-time stamp and can be saved as a CSV file and emailed for future reference, manipulation, or analysis to help determine trends and conditions over a long period of time. Use the app to attach photos and notes to the records creating a clear reference point for your work - ideal for record keeping at large sites.

The AC/DC clamp meter measures AC current to 1000 A AC, voltage (AC and DC), resistance, capacitance, frequency, temperature, duty cycle, and continuity. Special functions include auto ranging, data Hold, Max/Min readings, diode test, audible continuity check, over-range indication, low-battery indication, and auto power-off. The 1-3/16" (30 mm) jaw opening is ideal for use in small compartments or boxes with tightly arranged electrical wires. The meter also offers True RMS for more accurate current readings, and temperature measurement via a type K thermocouple.

The instrument is fully tested and calibrated to NIST-traceable standards for reliable measurements right out of the box, saving you time and money!

Key Features

• Get the most out of your data with our user-friendly mobile app
• Unlimited data storage based on smart device capacity
• Reliable measurements, guaranteed! Precalibrated to NIST-traceable standards
• Rugged double-molded housing provides increased durability
• Electronic overload protection prevents damage
• Large backlit LCD permits viewing in low-light conditions

Includes

Test leads, type K thermocouple, carrying case, 9 V battery, and NIST-traceable calibration.

SST1-H-36 SST1 Single Gas Detector, H2S 0-500ppm 3 Year Fixed Life (Hydrogen Sulfide) by WatchGas

The SST1 single gas detector provides up to three years maintenance free operation and is available in H2S, SO2, CO or O2 (2 year only) models. With its simple design it is perfect for users that are looking for ultimate protection while being easy to use, durable and cost effective. Simply turn on the device and it runs 24/7 for 2 to 3 years – no calibration, no battery replacement no charging and no stress. The device is easy to use and reduces the need for extensive training. The SST1 coupled with the SST Dock allows for the fastest bump testing on the market and makes fleet management extremely simple.

Applications

• Oil and gas upstream
• Oil and gas downstream
• Contractors
• Site maintenance
• Turn arounds and shutdowns
• Boiler rooms
• Steel plants
• Laboratories
• Shipping
• Power generation
• Mining

Features and Benefits

• Easy Setup: Near Field Communication built in as standard allows for a wide range of solutions depending on your needs. Simply pair with the WatchGas App to manage your fleet, bump, calibrate, assign or download event logs. See Tap & Go application note for more information on the benefits of NFC.
• Sensor: Using the latest in Solid State Technology our H2S, CO, O2, & SO2 offer stability and reliability over extreme temperatures and conditions. With its smaller form factor and the removal of traditional Electrolyte allows for a new standard in the single gas market.
• Display: With the largest LCD in its category the SST1's display shows months remaining.
• Rugged: Designed with the harshest environments in mind the SST1 offer an Ingress Protection rating of 67-68. The casing is a double shot housing that gives extra robustness while not compromising on quality. The screen protectors located either side of the display are to protect the LCD from scratching and is required due to the smaller sensor profile.
• Alert: As a safety device it is essential that the device clearly notifies users of the presence of gas. The SST1 has a 95dB alarm at 30 centimetres which is the industry standard and is required in loud industrial environments. High and Low alarms can be configured by the customer and automatically updated directly on the device or through the SST Dock.
• Cost Effective: Designed to be zero maintenance and remove the need for calibration the SST1 allows for 2 or 3 years of full up time. No sensor or battery replacements means no hidden costs and a one-year shelf life it is perfect for turn arounds and contractors.
