Vaisala is issuing a product recall for old models of the Veriteq compact lithium battery-powered dataloggers. The loggers in question were manufactured by Veriteq Instruments and sold as either the Veriteq Spectrum/Model 5 or private labeled by dataTaker as the DT1000-4000 Series. Veriteq was purchased by Vaisala in 2010.
In very rare cases, these loggers are subject to potentially experiencing overheating when using the device connected to a network via an external serial or USB cable. The serial line connection may unintentionally start to recharge the lithium-thionyl-chloride battery inside the datalogger. Although very unlikely, the overheating may in some instances cause the battery to breach its casing.
