Single Dock – Individual Use
Single Dock – Individual UseCompact charging dock for single-pump operations; makes it easy to set the pump to charge systematically after a shift.

Which Sampling Applications Can Be Performed with an Apex2?

Respirable Dust and SilicaRespirable dust and crystalline silica sampling according to standard methods using a suitable cyclone and filter.
Inhalable / Total DustPersonal particulate sampling with an IOM or method-compliant sampling head and filter cassettes.
Welding Fume and MetalSampling of metal particulates, welding fume, and process aerosols using suitable filter media and flow rates.
Gases and VapoursMethod-dependent active gas and organic vapour sampling using a low-flow adaptor and appropriate sorbent tubes/media.
Fibres / AsbestosPump platform suitable for fibre sampling applications using method-compliant filter cassettes and specified flow rates.
Bag SamplingThe pump's bag outlet feature supports gas bag sampling applications when used with suitable connections and procedures.

Smart Field Management with Calibration and Airwave

For accurate personal air sampling, the pump must be calibrated at the target flow rate with the sampling media in line. The Bluetooth® / Airwave connectivity of the Apex2 Plus and Pro models makes it easy to monitor and control the pump without disturbing the worker. Airwave does not replace an external primary flow calibrator; flow rate verification must be performed with an appropriate calibrator before and after sampling.

Frequently Asked Questions About TSI Casella Apex2

What flow range does the Casella Apex2 operate across?
According to current manufacturer information, the Apex2 operates in the 0.8–5 L/min medium-flow range. In low-flow applications, a range of 5–500 mL/min is supported with a suitable adaptor.
What is the difference between Apex2 Standard, Plus, and Pro?
All three models share the same fundamental pump performance, intrinsic safety, and motion sensor. The Plus adds Bluetooth, Airwave, PC data download, inlet pressure sensing, and a run duration timer. The Pro adds a programmable timer, TWA, and time-history data graphing.
Is the Apex2 suitable for intrinsically safe / ATEX use?
Intrinsically safe models of the Apex2 series are certified for use in hazardous areas. Current certification markings and zone classification of the target site must be verified prior to purchase.
Does the Apex2 comply with the ISO 13137 standard?
TSI specifies ISO 13137:2022 compliance in the current Apex2 Plus product information. The flow rate, media, and calibration requirements of the sampling method must also be observed.
Can calibration be performed via Bluetooth with the Apex2?
The Plus and Pro models offer Bluetooth and Airwave support. Pumps can be monitored and controlled remotely via Airwave. Flow calibration is performed before and after sampling using a suitable external flow calibrator; Bluetooth connectivity facilitates the field workflow and pump control.
What is the advantage of the 5-way Apex2 kit?
It simplifies managing five pumps within a single transport and charging infrastructure. In the 5-way kit, the manufacturer supplies a 5-way docking station, power supply, USB cable, and essential accessories alongside the pumps; this is practical for multi-member field teams and laboratories.
