The IP3D Series is built for engineers who need consistent, repeatable IP data without exotic workflows. This ultra-high voltage, high-power true three-dimensional time-frequency induced polarization measurement system has been refined through years of field use in mineral exploration, groundwater mapping, and engineering geology. Let me walk you through its practical advantages.
The Hyper3K transmitter delivers 3000V and 80A per unit (60 kW). You can stack units in series to reach 6000V or parallel them for up to 300A and 300 kW - whichever matches your ground resistivity. The chassis is compact (<50x40x30 cm) and weighs less than 45 kg, so two people can load it into a truck or carry it short distances. Protection features include open-circuit, short-circuit, over-temperature, over-current, over-voltage, and an emergency stop switch - you will not burn out the unit even if you make a wiring mistake. The transmitter supports time-domain IP (TDIP), frequency-domain IP (SIP), and spread-spectrum IP (SSIP). The latter sends multiple frequencies at once, cutting survey time dramatically. A built-in high-precision current sensor records full waveforms; the same data is broadcast in real time to all receivers via 4G or LORA. You never need to guess the injected current.
The IPU-4C receiver is a node-type four-channel unit encapsulated in a rugged IP67 housing. It measures just 13x13x16 cm and weighs 1.3 kg. Drop it? Rain on it? Submerge it briefly? No problem. Inside, a 32-bit Sigma-Delta ADC provides >180 dB dynamic range and an ultra-low noise floor of <6 nV/√Hz. This means you can measure tiny IP decays even near power lines or radio towers. The input impedance exceeds 1 GΩ, so you can use high-resistance electrodes without signal loss. Four acquisition channels can be configured as 1, 2, or 4 active channels, and the five terminals (N, E, W, S, G) allow cross layouts, L-shaped arrays, linear profiles, and orthogonal patterns. You get true 3D, 2.5D, or 2D surveys from the same hardware.
Each receiver contains a 120 Wh lithium battery that powers >15 days of continuous acquisition. You can leave an array of 100 receivers in the jungle for two weeks without visiting them. Storage is >256 GB of EMMC, enough for weeks of full-waveform recording. When you are ready to recover data, place the receivers on the WPS-12 wireless power station. This unit has 12 ports, each providing 30W wireless charging and 20 MB/s data download. Total download speed reaches 240 MB/s - faster than many wired USB connections. No need to open waterproof lids or plug in fragile connectors. The WPU single-port unit is also available for small crews.
Forget walking to each station. You can control every IPU-4C via Bluetooth from your mobile phone or tablet, viewing real-time results on the spot. For large 3D arrays, use 4G or LORA to send commands and receive status updates from a central computer. The system also supports NFC electronic tags for rapid equipment identification - just tap a phone to a receiver to see its serial number, battery level, and last data file.
