Replacement Pitot Tips
| The unique design of the Apex Modular Pitot Tip reduces
the collection of water droplets in the pitot lines. The lower
tube is self-draining while the offset in the upper tube acts
as water trap. The water can be easily cleared by tilting
the tip down or by back purging. Replacement tips for standard
Method 5 probes are MPT-6-181 and MPT-6-133
for probes with optional oversheath. Longer tips are available
for in-stack filtration. |

Air Cooled Method 5 Probe
| Apex Instruments offers Air Cooled Probes
up to 8 ft. in length, applicable for high temperature sources.
Concentric tubular design allows the cooling air to return
and exhaust out of the stack. The probe sheath is constructed
from stainless steel tubing while the liner, pitot, thermocouple
and nozzle union are constructed from inconel. A variable
speed high capacity blower is utilized for cooling. Order
blower separately. |

Probe (Tube) Heaters for Method 5 Probes
| Apex Instruments Probe Heaters for Method
5 Probes feature a rigid tube heater with coiled heating
element, electrical thermal insulation with integrated thermocouple
and power control cable seated in silicone-impregnated glass
insulation. Rigid mandrel design allows liner replacement
without removing the heating element. Actual tube length is
2 3/8 inches less than nominal length. Supplied with straight
blade plug with ground. 240V heaters are available at no additional
cost. Add “V” to end of part number. Recommended
maximum temperature: 260°C (500°F). |

from corrosion-resistant stainless steel alloy, modular 3/8
inch pitot tip with 1/4 inch stainless steel quick connects,
stack temperature thermocouple and an orsat line. Standard
lengths are 3 to 16 feet. Longer lengths are available by
request. To add a heater to probe sheath add “H”
to end of part number. 240V heaters are available at no additional
cost. Add “V” to end of part number. |

Inconel Method 5 Probe Sheaths (IPS-o)
|
The Apex Instruments Inconel Method 5 Probe Sheaths are
available for gas temperatures up to 1800°F. These include
a fixed 3/8 inch pitot tip with 1/4 inch stainless steel
quick connects, orsat line and high temperature MgO stack
temperature thermocouple. This features Apex Instruments,
Inc. unique and proprietary mounting clips that allow the
quad tubes to free float independently of the probe sheath.
Our inconel probe sheaths come standard with inconel unions
for nozzle and pitot (stainless steel optional). Order liners
separately.

Probe Liners
| Standard Probe Liners are constructed from 5/8 inch
diameter tubing and have #28mm ball joint attached. Liners
are available in borosilicate glass, quartz, stainless steel,
inconel and PTFE. PTFE liners and liners with integrated
nozzles require a ball joint adapter. In addition we also
offer glass and quartz liners with male 14/35 taper joint
for attaching to the appropriate nozzle eliminating the need
for the 5/8 inch union. |
