Digital Manometers and Pressure Loggers

The LEO 1 is an autonomous battery powered manometer with digital display designed for monitoring sudden pressure changes in a standalone unit. The LEO 1 features a micro-processor with a 5KHz fast peak function that can show Max and Min values of pressure spike or troughs. Pressure ranges are available from -1 to 3 Bar up to 0-700 Bar. The internal battery will provide up to 1,000 hours continuous operation. Accuracy is ±0.2%FS (0-50°C). The LEO 1 is available for safe area use and the LEO 1Ei for hazardous area installation.

Hazardous Area Approved

The LEO 2 is an autonomous battery powered pressure gauge with digital display from Keller. The LEO 2 uses a piezoresistive pressure cell that has undergone extensive pressure and temperature test, with individual adjustments for each unit for an improved accuracy of 0.1% FS. Pressure ranges are available from -1 to 3 Bar up to 0-700 Bar. The internal battery will provide up to 1,000 hours continuous operation. The LEO 2 is available for safe area use and the LEO 2Ei for hazardous area installation and both are available from stock.

Hazardous Area Approved

The LEO Record is an autonomous battery powered manometer with digital display designed for monitoring pressure and temperature in a standalone unit. The LEO Record uses a piezoresistive pressure cell. Pressure ranges are available from -1 to 3 Bar up to 0-2000 Bar. Internal memory for 57,000 readings and internal 3.6V Lithium battery allows up to 2 years operations. Logged data can be viewed in table or graph format and exported to MS Excel using the K114A and Kolibri Desktop software. Accuracy is ±0.1%FS and 0.5°C, operating temperature 0 to 50°C. The LEO Record is available as an intrinsically safe version from stock suitable for hazardous area installations.

The LEO Record CAPO is an autonomous battery powered manometer with digital display designed for monitoring pressure and temperature in a standalone unit. The LEO Record CAPO uses a capacitive ceramic pressure cell making it ideal for low pressure ranges. Available ranges as 30, 100 and 300mBar with either a relative or differential pressure reference and bi-directional ranges. Internal memory for 57,000 readings and internal 3.6V Lithium battery allows up to 2 years operations. Accuracy is ±0.2%FS and 0.5°C, operating temperature 0 to 50°C. The LEO Record CAPO is also available as an intrinsically safe version.

Keller Digital Manometer LEO 3 ACCURACY 0,1% LEO 3 combined digital manometer / display and pressure transmitter available for pressure ranges up to 1000 bar with 4-20mA output.

LEX 1 Digital Manometer is a highly precise pressure indicator with available pressure ranges up to 1000 Bar. The LEX 1 is a micro-processor controlled, digital pressure measuring instrument with integrated max.- and min- function for testing and calibration purposes. Standard accuracy is 0.05%FS with optional precision of 0.025%FS and 0.01%FS. The LEX1 is also available with ATEX certification for hazardous area use (intrinsically safe).

The Keller LEO 5 is a combined pressure and temperature indicator and data logger available for pressure ranges up to 1000 bar and featuring an IP66-rated stainless steel enclosure. The robust housing combines contemporary microcontroller-based electronics and capacitive-touch controls, operated through the environmentally-sealed safety glass front panel. The large backlit LCD display ensures readability in any lighting conditions. The LEO 5 combines the notable features of the LEO Record and LEX 1 digital pressure gauges, plus a peak function with 5kHz recording. The LEO 5 interfaces with a PC via USB and allows access to active measurements and recorded data including pressure, peak pressure, temperature and measurement interval. PC connection also allows device configuration, firmware updates and recharging of the integral accumulator power supply.
