Tinytag Data Loggers

Service Kits

These Service Kits contain the parts required for servicing and replacing the batteries of Tinytag data loggers.

Maintenance kits must be carefully matched to your specific hardware casing and profile to prevent moisture ingress or premature battery drain:

  • SER-9500: The universal field service kit containing a 1/2AA Lithium battery, replacement case gaskets, and fresh desiccant pouches for Ultra 2, Plus 2, View 2, Talk 2, and legacy Plus/IS loggers.

  • SER-9513: Specifically tailored battery replacement bundle for legacy, discontinued Tinytag Transit (TG-3080) loggers.

  • SER-9514: Double-duty service pack optimised with a slim profile CR2325 coin cell and instructions for Transit 2 (TG-4080/81) and Tinytag CO2 (TGE-0010/11) monitors.

  • SER-9525: Heavy-duty, marine-grade maintenance kit featuring deep-water replacement cells and pre-greased protective sealing O-rings exclusively for the fully submersible Tinytag Aquatic 2 (TG-4100).

Annual Recalibration

When you submit your data loggers for an annual re-calibration service, full preventative maintenance is already integrated into the standard procedure. As part of the calibration process, the internal lithium batteries, primary casing gaskets, and desiccant packs are automatically replaced with brand-new components to guarantee hardware integrity and maintain precise calibration baselines. Consequently, clients opting for annual factory calibration should not need to purchase standalone service kits, as all vital environmental seals and power cells are refreshed as part of the validation workflow. You can view these on the link below.

If you only wish to replace the battery and don’t need the full service kit, you can find these in the dedicated battery section.

Frequently Asked Questions

â–¶ Q: What is the primary purpose of a Tinytag Service Kit?
A: Tinytag Service Kits are comprehensive maintenance bundles designed to restore a data logger to its original operating specifications. They provide essential components, including replacement lithium batteries, specialised case gaskets (O-rings), and desiccant packs, necessary to maintain the hardware's ingress protection (IP) rating and operational reliability after a battery change.
â–¶ Q: Are Tinytag Service Kits universal, or do I need a specific one?
A: Service kits cover specific models and are not suitable for different ones. Loggers can have distinct housing designs, sensor ports, and pressure sealing requirements, selecting the wrong kit can compromise the device's water-tight seal. You must select the kit corresponding exactly to your logger series to ensure the O-rings and battery chemistry match the hardware housing requirements.
â–¶ Q: Why is it necessary to replace the desiccant pack included in the kit?
A: The desiccant pack is a critical component for maintaining accurate humidity measurements and preventing internal condensation. When a logger case is opened for maintenance, the internal electronics are exposed to ambient moisture. Replacing the exhausted desiccant pack with a fresh one ensures that any residual moisture is absorbed, preventing drift in relative humidity readings and protecting the internal circuitry from long-term corrosion.
â–¶ Q: How often should I perform a service on my data logger?
A: Service frequency depends on the sampling rate and the deployment environment. For loggers deployed in high-moisture or fluctuating temperature environments, or those utilising very fast sampling rates that deplete the battery quickly, maintenance should be performed as soon as the battery voltage drops to the manufacturer's recommended threshold. We recommend keeping a stock of the appropriate service kit on hand to ensure you can perform maintenance immediately upon battery depletion, avoiding gaps in your data records.
