What Tekbox does
Tekbox Digital Solutions is a Vietnam-headquartered specialty hardware manufacturer that designs, builds, and sells two product families: SDI-12-based environmental monitoring equipment and EMC pre-compliance test instruments. Founded in 2008 and operating from the Saigon Hi-Tech Park in Ho Chi Minh City with a second office in Singapore, the company serves engineers, product designers, agricultural operators, and organizations conducting EMC pre-compliance testing across global markets. The short_description provided in the source data frames the business around "automotive lighting, testing equipment, electronics, smart agriculture and environmental sensing products," though the live product catalog is concentrated on environmental sensors and EMC test gear rather than active automotive lighting systems.
The environmental monitoring portfolio is built around the SDI-12 bus standard for low-power digital sensor networks and spans more than ten sensor types (anemometers, wind vanes, pyranometers, soil moisture/temperature probes, leaf wetness sensors, ultrasonic level sensors, GPS, air temperature/humidity/barometric pressure, and compass/inclination), a full converter line (USB/RS232/RS485/MODBUS/UART to SDI-12), and SDI-12 sensor interfaces including 24-bit analog, PT100/PT1000, pulse, strain gauge, rain gauge, and latching relay modules. Remote telemetry is delivered through the TBS12B/S LoRaWAN RTU family and the TBSL1 multi-sensor RTU supporting LoRaWAN, LTE/WCDMA/GSM, Nb-IoT/Cat-M1, and WiFi communication over MQTT(S)/HTTP(S)/FTP(S) with NTP time sync.
The EMC pre-compliance line originated inside Tekbox's own automotive electronics lab, where internal use drove significantly higher type-approval success rates before the tools were industrialized. Today the test-equipment portfolio includes the TBMR-110M EMI analyzer (1 Hz to 110 MHz, -162 dBm/Hz noise floor, CISPR-16/ANSI/MIL-STD compliance), the TBVNA-6000 two-port vector network analyzer (0.1 Hz to 6 GHz), TBMA-series CISPR-compliant measurement antennas, TBL-series LISNs (0.7 µH to 50 µH, 5 A to 1000 A), TBMDA/TBLPA modulated RF amplifiers (100 kHz to 3 GHz, 150 mW to 25 W), RF current probes, near-field probes, TEM cells, coupling/decoupling networks (per IEC 61000-4-6 and CISPR 15), comb generators, IEC 61000-4-2 ESD targets, MIL-STD-461 antennas, and EMCview PC software that controls six major spectrum analyzer brands (Rigol, Siglent, R&S, Teledyne, BK Precision, Keysight). The 2024 TBL0225-2 LISN is built to ECSS-E-ST-20-07C Rev 1, opening a space-grade variant.
The business model is straightforward direct hardware sales through two dedicated e-commerce storefronts (sdi-12products.com for SDI-12 products and emcsupplies.com for EMC test equipment), supplemented by contact-for-pricing enterprise sales via the main website. EMCview is sold as a one-time analyzer-coupled or PC-coupled software license. Pricing is not publicly disclosed. Customer segmentation is vertical-based: environmental monitoring users (weather stations, precision farming, irrigation/flood-gate monitoring, soil-moisture networks) and EMC pre-compliance testers (engineers, design houses, smaller companies that cannot afford full compliance test house work). A partnership with Kipp&Zonen embeds the SP-Lite2 pyranometer inside the TBSSR1 SDI-12 pyranometer product.
