Portable and wireless
Honeywell Flex 5 Series
The Flex 5 Series is Honeywell's modular portable platform: one base unit that works as a pumped instrument for confined space sampling and as a wearable for personal protection, with swappable cartridges instead of separate devices.
What it is
Purpose and use
Honeywell designs the Flex 5 for fleets that have to cover several tasks with the same equipment. The device takes 4-way or 6-way diffusion cartridges or a 6-way cartridge with built-in pump, and the cartridges are field-replaceable — a configuration change no longer means a different instrument.
Connectivity is optional rather than permanent. Readings can be relayed at the moment of an alarm, or transferred when the instrument is docked, and the device works with Honeywell Safety Suite 2.0 for fleet management or with PC Lite for local set-up. NFC actionTAGS automate bump testing, calibration, accessory checks and permit-to-work steps, with the tag data encrypted to AES-128 or higher.
The Flex 5 was brought to market in 2026 as the successor to the Flex 4. Availability, part numbers and sensor ranges vary by region — we confirm them with Honeywell before quoting.

- Up to 6 sensors, of which 3 high power: up to 4 × 1 Series and 2 × 4 Series, selected from over 20 sensor types
- Three fundamental configurations: 4-way and 6-way cartridge (diffusion) and 6-way cartridge with built-in pump
- Sensors available for flammable gas and hydrocarbons (%LEL), carbon dioxide and oxygen (%VOL), VOC by photoionisation, ammonia, carbon monoxide, hydrogen sulphide, chlorine, chlorine dioxide, ethylene oxide, hydrogen, hydrogen chloride, hydrogen cyanide, hydrogen fluoride, nitric oxide, nitrogen dioxide, ozone, phosgene, phosphine and sulphur dioxide
- Certified temperature range −20 °C to +60 °C; operational range sensor dependent
- Ingress protection: independently tested IP66 and IP68 (diffusion), IP65 (pumped)
- Alarms: visual, vibrating and audible at 95 dB at 30 cm; 3 × instantaneous, TWA, STEL, negative drift, over limit, battery and system integrity

Stated according to the current manufacturer documentation. Binding data for a specific configuration is confirmed with the quotation.
Approvals and standards
- Global intrinsic safety approvals; suitable for Zone 0, 1 and 2 and Class I, Division 1 and 2 explosive atmospheres
- Approved for indoor, outdoor, onshore and offshore use by CSA (NRTL) to UL, CSA, IECEx and ATEX requirements
- Honeywell states that approvals are pending in parts of the world — we confirm the current position for your region before quoting
Application
Where it is used
- Confined space entry with the pumped configuration for pre-entry sampling
- Personal protection as a wearable, with the same base unit and a diffusion cartridge
- Fleets that need several gas configurations without holding several instrument types
- Operations where bump testing and calibration have to be traceable per device
Accessories and spare parts
- Field-replaceable 4-way and 6-way sensor cartridges, diffusion and pumped
- Extended battery
- NFC actionTAGS for users, accessories, bump test, calibration and locations
- Safety Suite 2.0 and PC Lite, docking and test gas for bump testing and calibration

FAQ
Questions about Honeywell Flex 5 Series
Does the Flex 5 replace our Flex 4 instruments?
The Flex 5 Series came to market in 2026 as the successor to the Flex 4. Whether a replacement makes sense for you depends on the remaining service life of your fleet and on whether the modular cartridges save you a second instrument type. We look at both before recommending anything.
Can one device be used both pumped and as a wearable?
Yes, that is the point of the platform: the same base unit takes a diffusion cartridge for wearable use and a 6-way cartridge with built-in pump for sampling. The cartridges are field-replaceable by users with appropriate training.
Is the Flex 5 already available in Germany?
Honeywell notes in the datasheet that approvals are pending in parts of the world and that availability should be confirmed by geography. We check the current position with Honeywell for each enquiry rather than promising a delivery date we cannot hold.
