HT Instruments HT-FLEX33 Flexible alternating Current Converter

HT Instruments HT-FLEX33 Flexible AC Current Sensor

The HT Instruments HT-FLEX33 is a flexible AC current sensor designed for measuring high currents in tight or hard-to-reach spaces. Its flexible Rogowski coil allows easy installation around large cables, conductors, or busbars where standard clamp meters cannot fit. When used with compatible measuring instruments, the HT-FLEX33 enables accurate AC current measurements up to 3000 A, making it ideal for industrial environments, power distribution systems, and maintenance applications.

Features:

  • Flexible Rogowski coil for measurements in confined or difficult-to-access areas
  • AC current measurement up to 3000 A (depending on configuration)
  • 33 cm coil length – perfect for large conductors and busbars
  • Lightweight, robust, and easy-to-handle design for daily professional use
  • Compatible with HT Instruments multimeters, clamp meters, and power analyzers
  • Ideal for industrial installations, power distribution, panel work, and maintenance tasks

HT Instruments also offers measuring instruments for PV installations with user-friendly operation and modern design to the highest quality standards.

Safety Instructions:

1. Do not measure voltages or currents in damp or wet environments.
2. Do not use the measuring device in environments containing explosive or flammable gas, materials, vapor, or dust.
3. Do not touch the circuit under measurement when no measurement is being performed.
4. Avoid touching exposed metal parts, unused measurement terminals, etc.
5. Do not perform measurements if you notice any irregularities such as deformations, cracks, leaking substances, or a non-functional display on the measuring device.
6. Exercise special caution due to the risk of electric shock when measuring voltages above 25 V in special environments (courtyards, swimming pools, etc.) and above 50 V in normal environments.
7. Use only original HT accessories.
