Keysight U127xA/AX Series Rugged Handheld Multimeter for Heavy Duty Use Down to -40°C
Models Keysight U1271A, U1272A, U1273A, U1273AX Handheld DMMs
The Keysight U127xA/AX series handheld multimeters are shaped perfectly to fit in your hand, with or without gloves on. Its non-slip ergonomic shape enables you to carry your DMM and perform measurements on the go easily. Large keys/switches and an illuminated, easy-to-read display make operation safe and easy - even in poor lighting conditions. This is especially true for the OLED display versions. The AX model is also suitable for outdoor use in winter due to its extended temperature range of -40...+55°C.
- Rugged handheld multimeters with all essential measurement functions.
- Intelligent additional features:
- U1272A and upwards: Zlow low impedance mode, minimizes stray voltages.
- U1272A and upwards: Smart Ohm minimizes false values caused by leakage currents.
- U1271A: Qik-V determines existence of AC or DC voltages.
- Low-pass filter.
- Dual display with 3000 counts.
- U1272A and upwards: AC+DC capable.
- Visual ("backlight alarm") and audible continuity indication in noisy environments.
- Handy non-slip housing.
- Dust and water resistant casing (IP 54 compliant).
- Large rotary switch and buttons that are easy to operate.
- Internal memory for datalogging.
- CAT III 1000 V and CAT IV 600 V safety rating.
- Model U1273A, AX with organic LED (OLED) display for high brightness level and wider viewing angles (up to 160 degrees).
- Model U1273AX with enhanced temperature range up to -40°C. For maintenance or troubleshooting during winter, in cold storage rooms, altitude up to 3000 metc.
